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.

+# Scripts Reference
+
+Conventions for `scripts/new-agent.sh` and any future scripts in this skill.
+
+## Contract
+
+All scripts in this skill must follow these rules:
+
+- **No interactive prompts** — agents run non-interactive; blocking on TTY input hangs indefinitely. Accept all input via positional arguments, flags, or environment variables.
+- **Structured output** — file paths and status messages to stderr; nothing to stdout unless a downstream tool needs to consume it.
+- **Idempotent** — "create if not exists" per file. The scaffold script skips any file that already exists; agents may safely re-run it.
+- **Meaningful exit codes** — `0` success, `1` invalid arguments or precondition failure. Document in `--help`.
+- **Self-contained** — no external package installs at runtime. The script uses only bash builtins and POSIX tools (`sed`, `mkdir`, `cat`).
+
+## Template variables
+
+The scaffold script uses `sed "s/AGENT_NAME/$AGENT_NAME/g"` to substitute the agent name into templates. Template files must use `AGENT_NAME` (all caps, no delimiters) as the substitution token.
+
+Do not add additional substitution tokens unless you update both the template files and the script in the same edit pass.
+
+## File placement
+
+The script creates files at paths determined by scope detection (plugin/APM / project / user). Scope is resolved by walking up from the root directory: a `type:`-bearing `apm.yml` at or above the root marks the package root (plugin/APM scope, single file); an `apm.yml` without a `type:` field is a marketplace-only manifest and is skipped, the walk continues upward. If no such `apm.yml` is found, the root resolving to exactly `$HOME` is user scope; anything else is project scope. If scope detection logic changes, update the `new-agent.sh` usage comment and `SKILL.md` Step 1 scope detection description in the same pass.
+
+## Error messages
+
+On failure, state: what went wrong, what was expected, what to try. Example:
+```
+Error: agent-name must use lowercase letters, numbers, and hyphens only.
+       No leading, trailing, or consecutive hyphens.
+       Received: 'My_Agent'
+```
+
+Vague errors leave agents unable to self-correct.
+
+## --help output
+
+Keep `--help` concise — it may enter the agent's context window. Include: usage line, argument descriptions with scope detection table, exit codes. Omit prose explanations.
