feat(kyberforge): execute plugin-to-apm marketplace conversion

Why:
ADR-0015 established that Microsoft APM (apm.yml + .apm/) should replace
this repo's hand-authored plugin.json/marketplace.json model, with those
files becoming compiled output of `apm pack` instead of files edited by
hand via the (now-retired) plugin-author/marketplace-author skills.
Issue #90 was the deferred execution of that decision, gated on #88
(apm tooling) and #89 (apm-native agent-author/skill-author routing).

Implementation notes:
- All six plugins (bin, core, git, gitea, kyberforge, lint) now carry
  apm.yml + .apm/{skills,agents,hooks} as their authoring source. Skills
  moved with a plain git mv (content-identical across targets). Agents
  were re-authored, not moved: per ADR-0016, .apm/agents/*.agent.md
  compiles verbatim to both Claude and Copilot, so plugin-scope agents
  now carry only name/description/model/source_keys -- no tools: field,
  no Claude-only knobs (isolation, maxTurns, effort, memory,
  permissionMode).
- Root apm.yml registers all 7 marketplace packages (6 local plus
  mattpocock-skills as a remote entry) under versioning: per_package,
  matching this repo's existing independent-plugin-versioning practice.
- .claude-plugin/marketplace.json and every plugin's plugin.json are now
  apm-pack-compiled output, verified against the prior hand-maintained
  content: same names/descriptions/versions/licenses/authors, only
  cosmetic serialization differences (JSON key order, owner email vs.
  url, Unicode escaping).
- plugin-author and marketplace-author are retired now that apm-based
  authoring fully replaces their job; kyberforge bumped 1.3.1 -> 1.4.0
  for that removal, and the root marketplace catalog bumped
  0.3.1 -> 0.3.2 to match, per the version-bump convention now
  documented in apm-workflow's reference docs instead of a dedicated
  script (apm has no native version-bump automation).
- Fixed hardcoded pre-.apm/ path assumptions across
  .pre-commit-config.yaml, .pre-commit-hooks.yaml,
  scripts/check-scope-walkup-sync.sh, scripts/sync-vale-styles.sh,
  scripts/check-vale-style-sync.sh, six plugins' root plugin.json
  (stale skills/hooks/agents pointer fields that check-manifests.sh
  validates), and several tests/*.bats and tests/*.sh fixtures --
  including a bats REPO_ROOT relative-path depth bug (10 files, one
  extra .apm/ directory level to walk up) and a vale probe-path
  isolation regression introduced mid-fix.
- Corrected empirically-wrong assumptions surfaced this session in
  apm-workflow/apm-install's own reference docs: `apm marketplace
  package add` does not accept local paths (only owner/repo remote
  shorthand -- local packages are registered by editing apm.yml's
  marketplace.packages[] directly); `apm compile` is a consumer-side
  AGENTS.md/CLAUDE.md generator, not the plugin.json producer, and
  hard-fails on skill/agent-only packages without --clean; `apm plugin
  init <name>` nests a stray subdirectory when run with a positional
  name arg from inside a same-named directory; no native Copilot
  marketplace output profile exists; .mcp.json is merged into the
  compiled plugin.json content-aware and target-scoped, with no
  dependencies.mcp entry needed for simple passthrough; pipx is the
  correct pip fallback on externally-managed Python environments.
- Renamed agent-author's copilot.agent.md template asset to
  copilot.agent.md.template so apm compile's recursive *.agent.md glob
  stops misparsing the placeholder template as a real agent primitive.

Impact:
plugin.json and marketplace.json are compiled artifacts from here on --
editing them by hand is no longer the workflow; edit apm.yml/.apm/ and
run apm pack. CONTEXT.md's Plugin/Plugin marketplace glossary entries
reflect this. ADR-0001 is marked superseded, ADR-0006 moot, and
ADR-0010 updated for the new .apm/agents/ path (project/user scope
unaffected, per ADR-0016). Full local verification: claude plugin
validate --strict on all 6 plugins, apm audit --ci, apm marketplace
check, check-manifests.sh, and the full test suite (165/165 bats,
13/13 shell scripts) all pass clean.

-description: >
-  Use when the user wants to review a repo's AGENTS.md file, says "audit this
-  AGENTS.md", "check my AGENTS.md", "is this AGENTS.md any good", or wants to
-  know if AGENTS.md is safe to commit — even if they don't use the word
-  "audit". Also invoke proactively after agentsmd-author creates or updates
-  AGENTS.md, or after a hand-edit made outside agentsmd-author. Audits a
-  target repo's AGENTS.md file(s) — root and any nested monorepo files — for
-  embedded secrets/credentials, structural completeness against the
-  agents.md common-sections checklist, and drift (referenced commands or
-  paths that no longer resolve against the repo). Produces a compact
-  findings report (findings only, no PASS noise) with Why and Fix per
-  finding. Do not use to audit CLAUDE.md, .cursor/rules, or other
-  provider-specific adapter files — that's provider-adapter-author's
-  self-contained concern. Do not use to fix or write AGENTS.md content — use
-  agentsmd-author instead.

-## Gotchas
-
-- Always run all three checks — this skill does a single combined pass, not staged/gated passes. Don't skip structure or drift checks just because a secrets FAIL was found.
-- Never inspect or mention provider-specific adapter files (`CLAUDE.md`, `.cursor/rules/*.mdc`, `copilot-instructions.md`, etc.) — that's out of scope. If one exists and duplicates AGENTS.md content, that's `provider-adapter-author`'s concern, not this skill's.
-- A missing common section (e.g. no "Security" heading) is informational, not a failure — not every repo needs every section from the checklist. Only flag a FAIL when the file is empty, entirely unfilled placeholder text, or contains a real embedded secret/stale reference.
-- Gather findings internally; don't narrate PASS/FAIL per check as you go — surface them only in the final report.
-
-## Step 1 — Run the validators
-
-```bash
-bash scripts/validate-secrets.sh <repo-root>
-bash scripts/validate-structure.sh <repo-root>
-bash scripts/validate-drift.sh <repo-root>
-```
-
-Each script walks the repo for every `AGENTS.md` file (root and nested, excluding `.git`, `node_modules`, `vendor`, and similar) and prints `FAIL`/`INFO`/`SUGGESTION` lines with `Why`/`Fix` (or `Note`) per finding. A nonzero exit means at least one FAIL was found in that dimension. If a script cannot execute (`python3` unavailable, Bash denied), fall back to manual review: scan for real-looking credentials, check common sections are present, and spot-check a few referenced commands/paths by hand.
-
-## Step 2 — Report
-
-Open with a coverage line:
-
-```text
-Checked: secrets · structure · drift
-```
-
-Then output only findings that were found, in this order within a repo: `### Secrets`, `### Structure`, `### Drift`. Omit a dimension heading entirely if it produced nothing — its absence confirms it passed. Report each finding verbatim as emitted by the scripts (they already carry file:line, Why/Fix or Note).
-
-Close with a result block:
-
-```text
-## Result
-
-PASS
-PASS · P info
-PASS (N suggestions) · P info
-FAIL (N fails)
-FAIL (N fails) · P info
-```
-
-INFO and SUGGESTION findings are observational — they never flip PASS to FAIL. Do not fix anything — this skill reports and proposes only. Point the user to `agentsmd-author` to apply fixes.
