test(mwp-1): Phase 5 — end-to-end regression proof (MWP1_14)

MWP1_14 proves the clone-after-push staleness is gone end-to-end:

1. Push C1/C2/C3 individually — each gets the correct generation. 2. Delete C3 from CommitGraph — simulates the RC-1 backfill gap that caused the staleness bug (parent in musehub_commits but absent from musehub_commit_graph). 3. Push C4 (parent C3) — Phase 2 backfill restores C3=gen 2, C4=gen 3. 4. Clone with want=[C4], have=[] — asserts all 4 commits (C1–C4) and C4's blob are in the assembled mpack.

WITHOUT the fix: C4 gets gen=0, the range scan (gen <= 0) misses C2 and C3, so the clone is incomplete. WITH the fix: C4 gets gen=3, all 4 commits are in the range and the clone is complete.

All 13 MWP1 tests GREEN.
