[CLAUDE] Docs: compact 3 file core (-273 dòng tổng)

STATUS.md (-52 dòng, -27%): archive 51 row Recently Done Phase 0-7 cũ
  → changelog/recently-done-archive-2026-04.md (file mới)
  Giữ 12 row mới nhất Phase 8/Session 5 + pointer archive.

HANDOFF.md (-147 dòng, -32%): bỏ 3 section duplicate
  - Versioned workflow quick ref → cross-ref workflow-contract.md §7bis
  - File đang active (90 dòng tree) → cross-ref PROJECT-MAP.md
  - Git state snapshot stale → cross-ref `git log --oneline -10`

migration-todos.md (-74 dòng, -35%): collapse Phase 6 iter 1+2 + Phase 7
  done parts thành 4 dòng paragraph. Giữ Phase 8/9 active + skill audit.

Quy tắc compact (rules.md §6 implicit):
  - Recently Done > 30 row → archive cũ vào changelog/recently-done-archive-{YYYY-MM}.md
  - Phase done >= 1 tháng → collapse thành 1 paragraph + cross-ref session log
  - Section duplicate file khác → cross-ref thay vì copy

Commit MD-only → CI skip (path filter gotcha #41).
