fix(intent): make first-run permission selection compact

[LadyBluenotes]

🎯 Changes

First-run intent install printed every discovered skill description before asking for input. A project with 14 packages and 82 skills produced roughly 27 KB of text before the first choice.

Replace that dump with a count summary and searchable package picker showing at most six options. Review puts selected packages first and lets users choose individual skills, inspect descriptions and exclusions, or view the exact configuration before saving. Allow-all remains a separate advanced choice with explicit confirmation.

Also reject empty search results before submission, remove the duplicate completion message, and update the install, configuration, and trust documentation.

Follow-up to #241. The original installer is unreleased, so this updates its existing minor changeset instead of adding a separate patch entry. The broader scopes of #221, #222, and #234 remain open.

✅ Checklist

• I have followed the steps in the Contributing guide.
• I have tested this code locally with pnpm run test:pr.

Validation: 601 unit tests and 73 integration tests passed, along with lint, typecheck, docs checks, and build. Final focused checks passed all 198 installer/CLI tests. Tested the 14-package/82-skill example in a terminal: search, package-to-individual selection, configuration preview without writes, and saving five exact permissions plus guidance. changeset status confirms one minor release and no patch release.

🚀 Release Impact

• This change affects published code; the existing unreleased installer changeset is updated.
• This change is docs/CI/dev-only (no release).
