feat(persistence): add expand-phase thread incarnation storage (#5216)
* 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
