CHANGELOG.mdmodified

    error semantics (`authorization_pending`, `slow_down`,
    `access_denied`, `expired_token`) are honored.
  - **Capability:** `device-code` added to `/api/v1/meta`.
 +- **REST: actions workflows + workflow_dispatch (S50 §13 part 1).**
 +  `GET /api/v1/repos/{o}/{r}/actions/workflows` lists the workflows
 +  discovered in `.shithub/workflows/` at the repo's default-branch
 +  HEAD (or `?ref=`); `GET .../workflows/{id_or_file}` fetches a
 +  single workflow by basename, full path, or a deterministic
 +  64-bit hash of the path. `POST .../workflows/{file}/dispatches`
 +  triggers `workflow_dispatch` with optional `ref` and a typed
 +  `inputs` map (choice / boolean / string with required/default
 +  enforcement, same semantics as the HTML "Run workflow" button).
 +  Workflow_dispatch input validation now lives in a shared
 +  `internal/actions/dispatch` package consumed by both the REST
 +  and HTML surfaces. Enable/disable knobs are deferred to a
 +  follow-up (needs a new `workflow_disabled` table); every listed
 +  workflow is reported as `state: "active"` for now.
 +- **Capability:** `actions-workflows` added to `/api/v1/meta`.
