Resolves #14011 Resolves #14012

Related: #13999 Related: #14010

Evidence: L2 unit/preflight evidence for the repair-progress and duplicate-coverage guard changes. The broader #13999 incident remains open until the live Memory Core repair completes and canonical backup/export parity is proven.

Summary

• Adds operator-visible Memory Core repair-defrag progress: coverage enumeration start/finish, per-collection coverage counts, 10%-bucket intact extraction, 10%-bucket missing-vector re-embed, and shadow-promotion start/finish.
• Guards Memory Core repair coverage selection against duplicate stale Chroma collection-name rows by requiring the coverage row to match the live collection id.
• Removes roadmap-placement guidance from ticket-create instead of replacing stale Project 12 wording with another planning rule.

Deltas from ticket

• #14011 also includes the duplicate collection-name coverage guard because the repair path can otherwise log or repair against a stale backing row.
• #14012 was narrowed after operator correction: ticket-create now removes roadmap-placement guidance entirely; planning placement is out of scope for this skill.

Post-Merge Validation

• Run npm run ai:defrag-memory -- --allow-memory-core from a visible operator terminal and verify repair logs show coverage enumeration, per-collection counts, and 10%-bucket extraction/re-embed progress before shadow promotion.
• Keep #13999 open until live repair and canonical backup/export parity are proven.
