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.

+# Commit operations
+
+Read-only commit history, scoped to a repo (optionally to one branch or one path). Call signatures
+below were verified live against the deployed `gitea-mcp` server via `ToolSearch` at authoring time,
+not copied from research docs, for the same drift-avoidance reason noted in `references/branches.md`.
+
+This domain has no prior skill precedent — it's new coverage added alongside branches because commit
+history is naturally scoped to a branch (a "what happened on this branch" question), not because it
+shares any tool family with branch create/delete.
+
+## `list_commits`
+
+**Parameters:**
+- `owner` (string, required)
+- `repo` (string, required)
+- `sha` (string, optional) — starting SHA or branch name; if omitted, gitea-mcp uses the repo's
+  default branch
+- `path` (string, optional) — restrict results to commits that touched this file/path
+- `page` (number, optional, default: `1`, minimum: `1`)
+- `per_page` (number, optional, default: `30`, minimum: `1`)
+
+**Call:**
+```
+list_commits owner: <owner> repo: <repo> sha: <branch-or-sha> path: <optional-path>
+```
+
+Dispatch defaults:
+- "commits on `<branch>`" → pass `<branch>` as `sha`.
+- "commits touching `<path>`" (no branch mentioned) → pass `path` alone, `sha` omitted (defaults to
+  the repo's default branch).
+- Both given → pass both; the result is history for that path, walked from that branch/SHA.
+- Neither given → omit both; this returns default-branch history, which is a reasonable default for
+  an open-ended "what's the recent history here" question.
+
+**Response:** one object per commit: `sha`, `html_url`, `created`, `message` (when available),
+`author` (`{name, email, date}`, when available).
+
+Paginate per the manual-pagination Gotcha in SKILL.md if you need more than one page of history.
+
+## `get_commit`
+
+**Parameters:**
+- `owner` (string, required)
+- `repo` (string, required)
+- `sha` (string, required)
+
+**Call:**
+```
+get_commit owner: <owner> repo: <repo> sha: <commit-sha>
+```
+
+**Response:** same shape as a `list_commits` entry, but always fully populated (`message` and
+`author` are guaranteed present, not conditional). Use this when the user asks about one specific
+commit by SHA rather than browsing history — `list_commits` entries may omit `message`/`author` in
+edge cases, `get_commit` will not.
+
+## Token scope
+
+Both tools are believed to require `write:repository`, even though they're read-only — inferred by
+analogy with the scope-gating principle in `overview.md` (Gitea gates reads behind write scope for
+repo-scoped operations), not a claim `overview.md` makes for commits by name: its explicit
+`write:repository` enumeration lists PR, branch, file, release, and tag operations, but doesn't
+mention commits. An earlier version of this doc claimed `write:issue` alone worked, based on
+empirical testing under a token that held both `write:issue` and `write:repository`
+simultaneously — that test didn't isolate the variable either. Treat this as unverified until
+tested under a token scoped to `write:issue` only (no `write:repository`).
