build(apm): consume holocron plugins through apm instead of plugin install

Why:
The repo published apm packages but consumed them the old way — `claude plugin install
<name>@holocron`, six plugins enabled per project. Dogfooding stopped one layer short of the
install tooling kyberforge itself ships.

Implementation notes:
- Root apm.yml declares the six packages as dependencies.apm git+path objects against the
  holocron remote. Object form over `<name>@holocron` aliases on purpose: an alias first needs
  `apm marketplace add`, which writes to ~/.apm/marketplaces.json — user scope, absent on a fresh
  clone. Unpinned against the default branch, matching the autoUpdate the native install had.
- apm.lock.yaml is committed; .claude/skills/, .claude/agents/ and apm_modules/ are gitignored
  regenerable install output. Committing the deployed skills would add a third mirror of content
  ADR-0017 already governs two copies of.
- .mcp.json is generated by apm from plugins/bin/.mcp.json, so the obsidian MCP server survives
  the switch.
- .claude/settings.json is reduced to {"hooks": {}}. apm replays the install into a scratch tree
  and diffs, so any repo-owned key there is permanent drift that fails apm-audit-ci. Nothing was
  lost: enabledPlugins was empty after the uninstall and the only hooks entry was PreToolUse: [].
- tests/run-bats.sh and tests/run-tests.sh exclude apm_modules/. It holds a full copy of every
  plugin, and a copied .bats file resolves its helpers against the dependency root rather than
  this repo — 334 tests, 167 failures before the exclusion.

Impact:
Skills are now unnamespaced — `git-commits`, not `git:git-commits` — because apm deploys plain
project skills with no plugin to prefix. AGENTS.md, CONTEXT.md and docs/spec/architecture.md are
updated accordingly. Root apm.yml now declares dependencies, which arms apm-audit-ci's
lockfile-exists check for the root manifest. External consumers are unaffected: the marketplace
manifests are untouched and `apm pack --check-clean` stays clean. Project scope only.

ADR: 0018

This repo consumes them through **apm**, not Claude Code's native plugin install: root `apm.yml` declares all six as `dependencies.apm` git+path entries against the holocron remote, and `apm install` deploys them into `.claude/skills/` and `.claude/agents/` (both gitignored).

 This repo dogfoods its own plugins. Before shelling out to git, gitea, or lint tooling directly, check whether an installed skill already owns the operation — it usually does:
 
-- Commits, branches, history, worktrees, remotes → `git:git-commits`, `git:git-branches`, `git:git-history`, `git:git-worktrees`, `git:git-remotes`
-- Pre-commit hook install/config/troubleshooting → `git:pc-run` / `git:pc-author`

+Names are **unnamespaced**. Under the old `claude plugin install` these were `git:git-commits`, `kyberforge:skill-audit`, and so on; `apm install` deploys each skill to `.claude/skills/<name>/` as a plain project skill, which has no plugin prefix to carry. The `<plugin>:` form no longer resolves here — it still does in any project that installs holocron natively, so a skill body written for both audiences should name the bare skill. Same for agents: `git-orchestrate`, not `git:git-orchestrate`.
 
 Fall back to raw shell only when no skill covers it.
 
 ## Setup and testing
 
-- Install git hooks via `git:pc-run`, wiring all three stages — this repo's `.pre-commit-config.yaml` has no `default_install_hook_types`, so a plain install silently skips `commit-msg` (Conventional Commits) and `pre-push` (the 13-hook gate described below).
-- Install the `apm` CLI — four pre-push hooks shell out to it: `apm-marketplace-check`, `apm-audit-ci`, `apm-pack-check-clean`, and `check-plugin-content-sync` (via `scripts/sync-plugin-content.sh`, which wraps `apm pack`). `apm-marketplace-check` and `apm-pack-check-clean` are bare `apm …` hook entries and `apm-audit-ci` is a `bash -c` loop calling `apm` once per package, so without it the push dies with an unhelpful "command not found". Use `kyberforge:apm-install`, or `curl -sSL https://aka.ms/apm-unix | sh`; verify with `apm --version`.
+- Run `apm install` to deploy this repo's own skills and agents into `.claude/skills/` and `.claude/agents/`. Both are gitignored install output, not authoring source — `plugins/<name>/.apm/` remains the only place to edit. The six dependencies in root `apm.yml` resolve from the holocron **remote**, unpinned against the default branch, so a `.apm/` edit is not visible to the running session until it is pushed and `apm install` re-runs. Needs the network, and needs `apm_modules/` (which it materializes) left gitignored. `apm install` also configures the `obsidian` MCP server into the repo's `.mcp.json`, carried over from `plugins/bin/.mcp.json`.
+- Do not add repo-owned keys to `.claude/settings.json`. apm treats that file as its own deployed artifact: `apm audit --ci` replays the install into a scratch tree and diffs, so anything apm would not have written there — an `enabledPlugins` block, a real `hooks` entry — is permanent drift that fails the `apm-audit-ci` pre-push hook. The file's committed content is exactly `{"hooks": {}}`. Machine-specific settings go in the gitignored `.claude/settings.local.json`, which apm does not deploy and the replay does not compare; shared enforcement belongs in `.pre-commit-config.yaml`.
+- Install git hooks via `pc-run`, wiring all three stages — this repo's `.pre-commit-config.yaml` has no `default_install_hook_types`, so a plain install silently skips `commit-msg` (Conventional Commits) and `pre-push` (the 13-hook gate described below).
+- Install the `apm` CLI — four pre-push hooks shell out to it: `apm-marketplace-check`, `apm-audit-ci`, `apm-pack-check-clean`, and `check-plugin-content-sync` (via `scripts/sync-plugin-content.sh`, which wraps `apm pack`). `apm-marketplace-check` and `apm-pack-check-clean` are bare `apm …` hook entries and `apm-audit-ci` is a `bash -c` loop calling `apm` once per package, so without it the push dies with an unhelpful "command not found". Use `apm-install`, or `curl -sSL https://aka.ms/apm-unix | sh`; verify with `apm --version`.
 - Install `jq` — required by `scripts/check-manifests.sh` and `scripts/sync-plugin-content.sh`, both pre-push. These at least fail loudly (`Error: jq is required but not installed`).
 - Install the `vale` binary — required by the `vale-audit-prefilter-skill`/`-agent` pre-commit hooks. Their `files:` patterns are `.apm/`-scoped: `^plugins/[^/]+/\.apm/skills/[^/]+/SKILL\.md$` and `^plugins/[^/]+/\.apm/agents/[^/]+\.agent\.md$`. Only the authoring source triggers them — a `SKILL.md` in the generated mirror matches neither pattern, so prose findings surface only when you edit the file you are supposed to be editing. Without the binary the hooks fail with a bare "command not found" and no install pointer. `brew install vale` (macOS), `snap install vale` (Linux), `choco install vale` (Windows), or see https://vale.sh/docs/vale-cli/installation/. No `vale sync` needed — the `Kyberforge` styles are committed under `plugins/kyberforge/.apm/skills/{skill-audit,agent-audit}/assets/vale/styles/`, not downloaded packages (see ADR-0014).
 - `vale` is also a **pre-push** dependency, not only pre-commit. `check-vale-style-sync` runs six glob-coverage probes by invoking `vale --config` — they are the only assertions in it that catch a `.vale.ini` glob typo, the failure mode where every text-level check stays clean while vale lints zero files. Missing `vale` is therefore a hard failure there. The opt-out is `CHECK_VALE_STYLE_SYNC_ALLOW_MISSING_VALE=1`, and it is **not** `SKIP=`: the hook still runs and still asserts everything verifiable from file text, but the six probes do not, and its summary says so explicitly — `Vale style sync check passed (text-level only, vale unavailable): … 0 glob probe(s) verified`. Use it only on a machine that genuinely cannot install `vale`, and read that summary line as "the glob axis was not checked", not as a pass.
 - Run `bash tests/run-tests.sh` before considering any change done — it runs every `test-*.sh` script in the repo plus the bats suite (`--bats-only` for just bats). First run auto-initializes the bats submodules; no manual `git submodule update` needed.
 - A suite that exits 77 because a dependency is missing is reported as SKIPPED, and does **not** fail an ad-hoc run. The pre-push hook invokes the same script as `--strict` (`RUN_TESTS_STRICT=1` is equivalent), where a skip **does** fail the push: at pre-push a skip means one of the dependencies above is absent on this machine, so the gate would otherwise report success having run fewer suites than it appears to. Without vale, for instance, three suites skip (`test-check-vale-style-sync.sh`, `test-vale-hooks-consumer.sh`, `test-vale-wrap.sh`) and the strict failure names each one and what to install.
-- `tests/run-bats.sh` derives the set of `.bats` files it expects from `git ls-files`, so a `.bats` file deleted from the worktree but still tracked in the index fails the run rather than silently shrinking the suite. Remove one with `git rm` (or stage the deletion) when the removal is intentional; an untracked new `.bats` file is picked up and needs no ceremony.
+- `tests/run-bats.sh` derives the set of `.bats` files it expects from `git ls-files`, so a `.bats` file deleted from the worktree but still tracked in the index fails the run rather than silently shrinking the suite. Remove one with `git rm` (or stage the deletion) when the removal is intentional; an untracked new `.bats` file is picked up and needs no ceremony. Both discovery walks (`tests/run-bats.sh` and `tests/run-tests.sh`) exclude `apm_modules/`: `apm install` materializes a full copy of every plugin there, and running a dependency's copy of a `.bats` file breaks its relative path to the bats helpers — 167 spurious failures before the exclusion landed.
 - Pushing runs 13 repo-defined pre-push hooks, not just the test suite — `run-tests` and `check-manifests`, plus generated-content drift gates (`check-plugin-content-sync`, `check-marketplace-mirror-sync`, `check-vale-style-sync`, `check-scope-walkup-sync`), artifact validators (`check-apm-agents-valid`, which runs agent-audit's `validate.sh` over every real `plugins/*/.apm/agents/*.agent.md`), apm's own gates (`apm-marketplace-check`, `apm-audit-ci`, `apm-pack-check-clean`), host validators (`validate-plugins`, `validate-marketplace`, both needing the `claude` CLI), and `check-release-needed`. Run `pre-commit run --hook-stage pre-push --all-files` locally — one command, the whole gate. That command reports **15**, not 13: pre-commit's own `meta` hooks, `check-hooks-apply` and `check-useless-excludes`, declare no `stages:` and so run at every stage including this one.
 - `apm-audit-ci` runs `apm audit --ci` once per manifest — the root one and each of the six plugin packages — because the root-only invocation audits the marketplace manifest and **nothing else**, and `apm-pack-check-clean` does not parse plugin `dependencies:` blocks either (verified: a malformed one passes `apm pack --check-versions --check-clean --dry-run` and fails `apm audit --ci` in that package's directory). It verifies two things and claims no more: each `apm.yml` parses as a valid APM manifest, and any package declaring dependencies has a consistent `apm.lock.yaml`. It does **not** enforce an org policy — apm discovers one from the git remote and only understands github.com and Azure DevOps, so against this repo's self-hosted Gitea remote it prints `No org policy found at unknown; enforcement skipped`. Do **not** "fix" that with `policy.fetch_failure_default: block` in `apm.yml`: it was tested and rejected, because with no reachable policy source it makes the hook exit 1 on every push forever.
 - `check-apm-agents-valid` derives its expected agent-file set from `git ls-files` (same pattern as `tests/run-bats.sh`), so an agent file deleted from the worktree but still tracked fails the run, and discovering zero agent files is an error rather than a pass. An untracked new agent file is still validated — the derivation is one-directional on purpose, so uncommitted work is not blocked but also cannot bypass the gate.
 - **Two** pre-push hooks need the network, for one shared reason: root `apm.yml`'s `marketplace.packages[]` contains exactly one remote entry (`mattpocock-skills`, `source: mattpocock/skills`), and resolving it needs a `git ls-remote`. `apm-marketplace-check` resolves every entry and is `always_run`, so it fails with `No cached refs (offline)`. `apm-pack-check-clean` (`apm pack --check-versions --check-clean --dry-run`) re-resolves the same entry and fails with `Error: Git network timeout during ls-remote`. Pinning the entry to an exact version does **not** remove the call — an exact pin still ls-remotes. `--offline` rescues neither. To push without a network, skip both using pre-commit's own mechanism: `SKIP=apm-marketplace-check,apm-pack-check-clean git push`. Skip those two alone — verified under `unshare -rn`, the other eleven pre-push hooks pass offline because they are real local checks, and adding one of them to `SKIP` disarms it silently. `apm-audit-ci` calls `apm` too but stays local: its org-policy discovery resolves nothing on this remote before any network call, so it does not join the pair above.
