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.

+# vale-run
+
+Run Vale (a prose/style linter) against an already-configured project and interpret its results.
+
+## What it does
+
+This skill covers invoking the `vale` CLI against files or directories, choosing an output format (human-readable CLI, `line`, or machine-parseable `JSON`), filtering by severity via `--minAlertLevel`, and handling exit codes in scripts and CI. It also covers resolving common runtime issues: false positives, format-specific inline suppression, and CI failures caused solely by Vale's non-zero exit code. It assumes the project already has a working `.vale.ini` and installed styles — setting those up is the sibling `vale-config` skill's job.
+
+## Usage
+
+```
+/vale-run
+```
+
+Describe what you want to lint and how (human-readable output, CI/JSON output, filtered by severity). The skill will pick the right flags and, if results include false positives, walk through the narrowest applicable fix.

+## Gotchas
+
+- Vale's exit code is driven by `error`-level alerts only. `warning` and `suggestion` alerts are reported but still exit `0`. `MinAlertLevel` and `--minAlertLevel` control display, never the exit code — no flag makes warnings fail. A rule that must gate CI or a commit hook has to be `level: error`. This is the single most common way a Vale gate silently passes everything.
+- `vale ls-config` prints the fully-resolved, currently active configuration as JSON — the fastest way to check why a rule "isn't applying" is what's actually active, not what's written in `.vale.ini`.
+- Inline suppression syntax is format-specific: Markdown uses HTML comments `<!-- vale off -->` / `<!-- vale on -->`, MDX uses `{/* vale off */}` / `{/* vale on */}`, Org mode uses `# vale off` / `# vale on`. The MDX form does nothing in a plain `.md` file — the alert still fires. Don't assume one syntax works across formats.
+- Before calling the `vale` binary directly, check whether the target repo documents its own wrapper script for Vale (look in its README, CONTRIBUTING docs, pre-commit config, or a `scripts/` directory). Some projects wrap `vale` to work around real bugs — e.g. a scope that silently stops matching multi-line YAML block-scalar frontmatter fields — and calling bare `vale` in a repo that has such a wrapper silently skips whatever the wrapper works around. If a wrapper is documented, invoke it with the same arguments instead of calling `vale` directly; otherwise fall back to the default below.
+
+## Running vale
+
+Default invocation (when the target repo has no documented Vale wrapper — see Gotchas):
+
+```bash
+vale <path-or-glob>
+```
+
+Key flags:
+
+| Flag | Purpose |
+|---|---|
+| `--output=<style>` | Output format/template: `CLI` (default, human-readable), `line` (compact, one alert per line, good for grep/piping), `JSON` (for programmatic parsing), or a custom template. |
+| `--minAlertLevel=<suggestion\|warning\|error>` | Overrides `MinAlertLevel` from `.vale.ini` for this run only, without editing config. Filters what is displayed; does not affect the exit code. |
+| `--no-exit` | Suppresses the nonzero exit that `error`-level alerts would otherwise cause; a no-op when no rule is `error`-level. Use in CI stages that should surface lint output without hard-failing the build. |
+| `--ignore-syntax` | Treats input as plain text, skipping format-aware parsing — use when a file's syntax-aware parser produces noisy or wrong results. |
+
+`vale sync` downloads the packages/styles declared in `.vale.ini` — that's a one-time-per-change setup step (vale-config's territory), not part of a normal lint run. If a run behaves as though no styles are active, that's a sign `vale sync` hasn't been run yet, not a `vale-run` problem.
+
+Prefer `--output=JSON` whenever the caller (a script, a CI step, another agent) needs to act on individual alerts rather than just get a pass/fail signal — `CLI` and `line` are for humans reading the terminal.
+
+## Fixing false positives
+
+Scope the fix as narrowly as possible, in this order:
+
+1. **Mentioning banned phrasing rather than using it**: wrap it in backticks or a fenced code block. Vale skips code spans and fences, so no suppression is needed at all. Try this before any suppression markup.
+2. **One-off**: inline-suppress the specific text run with the format's `vale off`/`vale on` markup.
+3. **Recurring known-exception string, one rule**: disable that specific rule for that specific match inline (e.g. `<!-- vale Style.Redundancy["ACT test","OTHER"] = NO -->` ... `= YES`), rather than the whole rule.
+4. **Known project term failing spell check**: add it to the style's `ignore` list, not an inline suppression.
+
+Never disable a rule project-wide to fix one false positive — editing `.vale.ini`/`BasedOnStyles` is vale-config's job, and it silences the rule everywhere, not just the false-positive case.
+
+If output looks wrong because Vale mis-parsed a file's format, rerun with `--ignore-syntax` before assuming the rule itself is broken.
+
+For CI that fails solely because Vale returned non-zero on `error`-level alerts — not because the content is wrong for that pipeline stage — add `--no-exit` rather than disabling the rule. If the failing alerts are warnings or suggestions, Vale is not what failed the build; look elsewhere.
+
+If setting up Vale as a pre-commit hook or need the full inline-suppression/spelling-ignore syntax reference, read `references/troubleshooting.md`.

+
+## Inline suppression syntax by format
+
+Markdown uses HTML comments — the MDX `{/* */}` form does not suppress anything in a plain `.md` file:
+```markdown
+<!-- vale off -->
+This text will be ignored.
+<!-- vale on -->
+```
+
+MDX:
+```mdx
+{/* vale off */}
+This text will be ignored.
+{/* vale on */}
+```
+
+Org mode:
+```org
+# vale off
+This text will be ignored.
+# vale on
+```
+
+## Disabling a specific rule for specific matches
+
+Targets one rule and specific known-exception strings, then re-enables — the preferred fix for a recurring false positive on a specific term, since it keeps the rule active everywhere else:
+
+Markdown:
+```markdown
+<!-- vale Style.Redundancy["ACT test","OTHER"] = NO -->
+This is some text ACT test
+<!-- vale Style.Redundancy["ACT test","OTHER"] = YES -->
+```
+
+MDX:
+```mdx
+{/* vale Style.Redundancy["ACT test","OTHER"] = NO */}
+This is some text ACT test
+{/* vale Style.Redundancy["ACT test","OTHER"] = YES */}
+```
+
+## Ignoring words in spell check
+
+The `spelling` check accepts an `ignore` list of external plain-text files, so project-specific terms don't need touching the dictionary:
+
+```yaml
+extends: spelling
+message: "Did you really mean '%s'?"
+level: error
+ignore:
+  - ignore1.txt
+  - ignore2.txt
+```
+
+## Plain-text fallback
+
+If a file's syntax-aware parsing produces noisy or incorrect results (an unsupported or malformed format), rerun with `--ignore-syntax` to treat it as plain text instead of relying on the format-specific parser.
+
+## CI failing unexpectedly
+
+Only `error`-level alerts make Vale exit non-zero; `warning` and `suggestion` alerts are printed but exit `0`. If a CI job fails solely because of `error`-level alerts — not because the content is actually wrong for that pipeline stage — add `--no-exit` rather than suppressing the rule itself. This preserves the lint output while not gating the build on it. If the alerts are warnings or suggestions, Vale did not fail the job — look elsewhere.
+
+## pre-commit integration
+
+Vale ships a pre-commit hook definition. A typical setup runs `vale sync` once (with `pass_filenames: false`) plus the actual lint pass with CI-appropriate flags:
+
+```yaml
+repos:
+  - repo: https://github.com/errata-ai/vale
+    rev: 16d3a7f
+    hooks:
+      - id: vale
+        name: vale sync
+        pass_filenames: false
+        args: [sync]
+      - id: vale
+        args: [--output=line, --minAlertLevel=error]
+```
+
+If the project has documented a wrapper script for a known Vale scope/escaping limitation (see the Gotchas section of `SKILL.md`), point the second hook's `entry:` at that wrapper instead of at bare `vale`, even though the hook's `repo`/`rev`/`id` still come from the upstream definition above — only the invocation target changes:
+
+```yaml
+      - id: vale
+        entry: <path-to-project-wrapper>
+        args: [--output=line, --minAlertLevel=error]
+```
+
+Using the upstream hook's bare `vale` entry in a project that has such a wrapper reintroduces exactly the bug the wrapper exists to fix.
+
+## CI output for machine parsing
+
+```bash
+$ vale --output=JSON README.md
+```
+
+Use `--output=JSON` when a CI step needs to parse results programmatically rather than read the default CLI-formatted output.
