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.

+  Use when reading or writing Gitea issues: listing repo issues, getting a single issue's details/
+  comments/labels, creating an issue, updating its state, adding or editing comments, applying
+  labels via issue_write, or searching issues/PRs across repositories. Triggers on "create an
+  issue", "what issues are open", "get issue #N", "close issue #N", "comment on issue #N", "search
+  issues for X" — even when the user doesn't say "Gitea" explicitly. Composes gitea-labels-
+  milestones for all label inference/resolution and milestone lookup — do not use this skill to
+  manage label or milestone definitions themselves (create/edit/delete a label, create/close a
+  milestone), that's gitea-labels-milestones directly. Do not use for pull requests (use gitea-prs)
+  or for local git branch/commit work (use gitea-branches or git-branches).
+
+compatibility: Requires Gitea MCP server configured with write:issue and write:repository token
+  scopes. Requires git remote "origin" pointing to the Gitea instance for owner/repo resolution
+  when invoked directly by a human; an orchestrating caller (e.g. gitea-workflow) may pass
+  owner/repo already resolved.

+## Gotchas
+
+- **`list_issues` has no `type` or `milestones` parameter — despite `api-reference.md` documenting both.** The live MCP schema (re-verified via `ToolSearch` at authoring time — see `references/sources.md`) only accepts `owner`, `repo` (required), `state` (default `"all"`), `labels` (array of label *names*), `since`, `before` (ISO 8601), `page`, `per_page` (default 30). This tool provides no way to filter issues-vs-PRs or by milestone. Since issues and PRs share one number space, `list_issues` results can include PR entries with no client-side filter to exclude them. If you need to know whether a specific number is a PR, call `issue_read method: "get"` and check `is_pull` — that field only appears on the single-item response, never in a list item. This exact drift (a prior skill trusted the research doc's `type` param and broke) is why this skill's reference files were re-verified live rather than copied from `api-reference.md`.
+- **`search_issues` does have a working `type` filter** (`"issues"` | `"pulls"`) — unlike `list_issues`. Its `labels` parameter is also shaped differently: a comma-separated string, not an array of names.
+- **Labels are numeric IDs on write, name strings on read.** `issue_write`'s `labels` parameter (used by `add_labels`/`replace_labels`) takes IDs. `list_issues`/`issue_read` return names. Never resolve this yourself — compose `gitea-labels-milestones` (see `references/enrichments.md`) to get IDs.
+- **Milestone on `issue_read` is `{id, title}`** — an object, not a bare string. This skill only ever needs the `id`. (The bare-title-string case only happens on the PR side, which is `gitea-prs`' problem, not this skill's.)
+- **Closing-keyword auto-close behavior is plausible but unconfirmed in our research docs.** Our research docs confirm Gitea does NOT auto-close an issue on a plain PR merge (unlike GitHub) — closing keywords like `Fixes #N`/`Closes #N` in a commit message are not documented one way or the other. After a PR merges (a `gitea-prs` operation), always re-check the issue's state here via `issue_read method: "get"` before deciding whether to close it manually — closing an already-closed issue is a harmless no-op, but don't assume a manual close is always needed.
+- **Pagination is manual.** `list_issues` and `search_issues` return one page at a time. Iterate `page: 1, 2, ...` until the returned count is less than `per_page`.
+- **HTTP 404 may actually mean 403.** Gitea hides permission errors as not-found. If a call 404s unexpectedly, verify the token holds `write:issue` scope (see `references/issues.md`'s Token scope note) before concluding the issue doesn't exist.
+
+## Step 1 — Resolve owner and repo
+
+Before any tool call, extract `owner` and `repo` from the git remote (skip this if an orchestrating caller already passed them in):
+
+```bash
+git remote get-url origin
+```
+
+If origin is not set or the URL is not a Gitea URL, stop and report: "No Gitea remote found — set origin to your Gitea instance URL."
+
+## Step 2 — Dispatch
+
+| Invocation | Action |
+|---|---|
+| `/gitea-issues` or `/gitea-issues list` | List issues (optional state filter) |
+| `/gitea-issues create` | Create an issue from conversation context — infers labels, checks milestone fit, applies a configured default assignee if set |
+| `/gitea-issues <N>` | Get issue details (flag it as a PR if `is_pull: true`) |
+| `/gitea-issues <N> comments` | Get an issue's comments |
+| `/gitea-issues close <N>` | Close an issue |
+| `/gitea-issues comment <N>` | Add a comment from conversation context |
+| `/gitea-issues search <query>` | Cross-repo search via `search_issues` |
+
+For full parameter detail on `list_issues`/`issue_read`/`issue_write`, read `references/issues.md`. For `search_issues`, read `references/search.md`. For the create-flow enrichments (label inference, milestone assignment, assignee workaround, dependency-linking), read `references/enrichments.md`.
+
+## Step 3 — Execute
+
+### list (default)
+
+Call `list_issues owner: <owner> repo: <repo> state: <"open"|"closed"|"all", default "all">`. Remember: results may include PR entries (see Gotchas) — if the caller needs issues only, this tool cannot filter that server-side; note the limitation rather than silently mislabeling PR entries as issues.
+
+### create
+
+1. Extract `title` and `body` from conversation context (the most recent task, bug description, or explicit statement). Fall back to an empty body if nothing is available.
+2. Run the enrichment sequence in `references/enrichments.md`: infer labels (composing `gitea-labels-milestones`), check for a clearly-fitting open milestone (composing the same skill), and check for a configured default assignee.
+3. Call `issue_write method: "create" owner: <owner> repo: <repo> title: <title> body: <body> labels: [<resolved IDs, or omit>] milestone: <resolved ID, or omit> assignees: [<default login, or omit>]`.
+4. Fire immediately — no confirmation step for the create itself.
+
+### `<N>` (get)
+
+Call `issue_read method: "get" owner: <owner> repo: <repo> issue_number: <N>`. If `is_pull: true`, report that this number is actually a PR and suggest `gitea-prs` for full detail.
+
+### `<N> comments`
+
+Call `issue_read method: "get_comments" owner: <owner> repo: <repo> issue_number: <N>`.
+
+### close `<N>`
+
+Call `issue_write method: "update" owner: <owner> repo: <repo> issue_number: <N> state: "closed"`. No `method: "close"` exists.
+
+### comment `<N>`
+
+Extract the comment body from conversation context (same sourcing as create). Call `issue_write method: "add_comment" owner: <owner> repo: <repo> issue_number: <N> body: <body>`.
+
+### search `<query>`
+
+Call `search_issues query: <query>`, adding `owner`, `state`, `type`, or `labels` filters if the request narrows scope (e.g. "search open PRs for X" → `type: "pulls" state: "open"`).
+
+## Step 4 — Report
+
+For reads: a compact table or numbered list — number, title, state, labels, milestone.
+
+For writes: confirm what was created/updated with the issue number and URL if returned.
+
+For errors: surface the HTTP code and message; check token scope per the Gotchas if a 404 looks wrong.
