feat(persistence): PR6 T6.5 — Run/Feedback/RunEvent repos workspace_id
`RunRepository` (put / get / list_by_thread / delete), `FeedbackRepository`
(create / get / list_by_run / list_by_thread / list_by_thread_grouped /
upsert / delete / delete_by_run), and `DbRunEventStore` (put / put_batch /
list_messages / list_events / list_messages_by_run / count_messages /
delete_by_thread / delete_by_run) all accept
`workspace_id: str | None | _AutoSentinel = AUTO`.
- Write paths stamp `workspace_id` from the contextvar (same shape as
the existing `user_id` stamping). For event writes the soft-read
`_workspace_id_from_context()` mirrors `_user_id_from_context()` so
background worker writes without a contextvar leave the column NULL —
consistent with PR5's nullable-during-backfill stance.
- Read paths get an extra `WHERE workspace_id = :wid` clause when the
resolved value is not None.
7 new tests (3 RunRepo + 2 Feedback + 2 RunEvent) prove cross-workspace
reads see zero rows. 92 existing run / feedback / event tests stay green.
