Re-arm projection rows parked as terminal Codex collisions #4327

#4326 (Fixes #4279) stops a stored session's differing project_path from refusing a Codex rollout as a collision, and stops parked terminal rows from keeping every pass backpressured. Rows already parked terminal on existing profiles (for example the beta.88 profile in #4279) are not re-armed, so their dropped message text stays missing until a full projection rebuild.

Acceptance: on upgrade, rows parked terminal only because of the project_path mismatch #4326 now accepts are re-armed once and project their messages. Genuine collisions (transcript_path, lineage, project_key) stay parked. A test seeds a profile with such a parked row and shows the messages appear after one pass.
