refactor(repository): introduce typed LockArrayRepositoryHandle

Share LockArrayRepository via Rc<RefCell<_>> while preserving the PHP
?LockArrayRepository type strength: Request.locked_repository, Locker
::get_locked_repository, and the installer create_* helpers now thread
the typed handle instead of an owned LockArrayRepository, and pool
builder identity check becomes a strict ptr_eq via widening into
RepositoryInterfaceHandle.
