feat: plan files always show review status (v0.11.1.1)

[garrytan]

Summary

• Every plan file created through a gstack skill now gets a ## GSTACK REVIEW REPORT section before exiting plan mode — even if no formal reviews have run yet
• Added Plan Status Footer to generateCompletionStatus() in the preamble (~25 lines)
• If a review skill already wrote a richer report, the preamble version skips
• If no reviews exist, writes a "NO REVIEWS YET" placeholder with links to /autoplan and individual reviews

Test Coverage

All new code paths have test coverage.
