HOLD - Add Claude Code Plugin setup page

[samgutentag]

⚠️ Blocked: Plugin not yet in official directory

The trunk-io/claude-code-plugin repo is public, but it is not listed in the official Anthropic plugin directory (anthropics/claude-plugins-official) yet. The install command in this page (/plugin install trunk@claude-plugin-directory) won't resolve until that listing lands. This docs page should ship alongside or after the directory listing PR.

Direct install (works now):

/plugin install trunk@https://github.com/trunk-io/claude-code-plugin

Summary

The new claude-code-plugin.md page is well-structured and the navigation wiring (summary.md, README.md) looks correct. However, there is one blocking issue and a few minor style nits.

Blocking

• Line 12 — The primary install command /plugin install trunk@claude-plugin-directory is broken until the plugin lands in the official Anthropic directory (explicitly called out as a blocker in the PR description). The page should either lead with the working direct-URL install (/plugin install trunk@https://github.com/trunk-io/claude-code-plugin) or add a clear caveat, before this page ships.

Non-blocking

• Line 17 — "run /plugin from Claude Code" is vague; the exact command isn't spelled out.
• Line 42 — "Say yes" is informal; "Confirm to apply" is more consistent with the rest of the doc's tone.
• Line 58 — "copy-pasteable" is informal; "ready-to-paste" reads better in docs.

Inline suggestions posted for all four items above.

"Say yes" is more casual than the rest of the document's tone. Consider something like:

Suggested change

	Trunk analyzes the test, explains the root cause (race condition, shared state, time dependency, etc.), and shows a proposed fix with a diff. Say yes to apply the changes directly.
