fix: evict stale project engine delegate on delete to prevent assert self._db crash

Deleting a project closed its store but left the delegate cached in _project_engine_delegates; re-creating a same-name project then reused the zombie engine and crashed in get_session. delete() now closes and evicts via _close_project_engine_store (also covers non-active deletes), the delegate cache self-heals when a cached store is closed, and _engine_for_project reopens a closed store for the non-evictable root engine case.
