fork_session passed each source message's metadata dict by reference into the new session. add_message() -> _persist_message() stamps _db_id (and timestamp) onto that dict in place, so persisting the fork overwrote the SOURCE messages' _db_id with the forked rows' ids — silently breaking edit/delete-by-id on the original conversation. Copy the metadata dict per message so the fork and source no longer alias. Adds tests/test_fork_session_metadata.py asserting the source session's message metadata is unchanged after a fork.
