+- **REST: actions caches (S50 §13 part 4 — §13 closure).** New

+  migration `0065_workflow_caches` adds the `workflow_caches` table

+  keyed on `(repo_id, cache_key, cache_version, git_ref)` with

+  size + last_accessed_at + object_key columns and a unique

+  constraint. REST surface:

+  `GET /api/v1/repos/{o}/{r}/actions/caches` (paginated; optional

+  `?key=` and `?ref=` filters; standard `Link:` headers; sorted

+  recency-DESC by `last_accessed_at`),

+  `DELETE .../actions/caches/{cache_id}` (single delete with

+  cross-repo 404 guard + best-effort async S3 cleanup),

+  `DELETE .../actions/caches?key=...[&ref=...]` (bulk delete by

+  key; idempotent — 204 even with zero matches). The runner-side

+  upload protocol that POPULATES this table is a future sprint;

+  this REST surface lands first so operators have an audit + purge

+  seat for when caches arrive.

+- **Capability:** `actions-caches` added to `/api/v1/meta`.
