Review: Approve ✓

This is a well-structured documentation addition that clearly explains the manual release process.

What's Good

• Clear step-by-step workflow with numbered steps
• Includes all necessary commands (version bump, build, DMG creation, GitHub release)
• Documents the code signing situation and the required xattr workaround for users
• Consistent with existing CLAUDE.md formatting and tone

Minor Observations (non-blocking)

1. The DMG output path uses /tmp/ which works but could be noted that this is ephemeral - fine as-is since it's just a staging location before upload.
2. The --notes placeholder in gh release create is a good reminder to add real notes.

No bugs, no security issues, no code changes to test. LGTM.
