fix(push/dry-run): align --dry-run commit walk to live have-negotiation (muse#32)

Use _all_known_have_anchors for the commit walk boundary in dry-run mode, matching the live path which reads ALL remote branch heads after GET /refs. Previously, dry-run used only get_remote_head(remote, push_branch) — a single-branch tip that ignored sibling refs, causing over-counting when a sibling branch had already been pushed.

After this change, both dry_commits and dry_objects derive from the same `have` set. Dry-run counts equal the live push when tracking refs are fresh (after muse fetch).

Tests: DR_01 (red→green, 2 variants), DR_02 (object parity, 2 variants). Adjacent corpus: 85 passed, 0 regressions.
