* [2.31.0] Reduce context token usage by 79%, include recent community contributions

The plugin was consuming 316% of Claude Code's description character budget
(~50,500 chars vs 16,000 limit), causing components to be silently excluded.
Now at 65% (~10,400 chars) with all components visible.

Changes:
- Trim all 29 agent descriptions (move examples to body)
- Add disable-model-invocation to 18 manual commands
- Add disable-model-invocation to 6 manual skills
- Include recent community contributions in changelog
- Fix component counts (29 agents, 24 commands, 18 skills)

* Fix: keep disable-model-invocation off commands called by /lfg, rename xcode-test

- Remove disable-model-invocation from test-browser, feature-video,
  resolve_todo_parallel — these are called programmatically by /lfg and /slfg
- Rename xcode-test to test-xcode to match test-browser naming convention

* Fix: keep git-worktree skill auto-invocable (used by /workflows:work)

* feat(converter): support disable-model-invocation frontmatter

Parse disable-model-invocation from command and skill frontmatter.
Commands/skills with this flag are excluded from OpenCode command maps
and Codex prompt/skill generation, matching Claude Code behavior where
these components are user-only invocable.

Bump converter version to 0.3.0.
