fix(stack): harden merge cleanup and stranded repair#31

Detach clean sibling worktrees that own a just-landed branch before deleting the local branch during stack merge cleanup. Dirty target owners now fail before hosted merge, matching descendant repair preflight behavior.
Use persisted child anchors that still match landed backup refs as replay boundaries after a partial squash-merge repair. This keeps later sync repairs from replaying already-squashed parent commits when the child has already been reparented to trunk.

Merged directly to main (rebased cleanly after #30 landed). Authorship preserved. Thanks @aryasaatvik! |

If stack merge persists the landed state but aborts before descendant repair, a later stack sync --apply can lose the correct replay boundary. In squash-merge repos, the child then replays both the already-squashed parent commits and its own, producing avoidable conflicts. Use the persisted branch anchor as a fallback replay boundary when the child is already parented to trunk and the stored anchor matches a backup/landed-* head, so stranded descendants replay only their own commits.

Summary
Fix two stack merge repair failure modes: landed branches checked out in clean sibling worktrees are released before cleanup, and stranded squash-merge descendants can recover their persisted replay anchor.
