* feat(persistence): expand thread incarnation storage Add nullable thread and MCP task incarnation columns while preserving mixed-version writes. New thread records receive stable incarnation IDs, and new task rows copy the matching owned or shared thread incarnation without changing any read, claim, session, or deletion behavior. * test(persistence): pin incarnation rollback compatibility * test(api): pin internal thread response boundary * fix(persistence): rebase incarnation rollout after projects --------- Co-authored-by: CorgiBoyG <CorgiBoyG@users.noreply.github.com>
