infra(sdk): add all-required sentinel to CI workflow

Adds the `all-required` job to `.gitea/workflows/ci.yml` so the
`Test / all-required (pull_request)` context is available as a
single hard-gate status check for branch protection.

Uses `toJSON(needs)` + Python parser (matching molecule-core pattern)
to reliably detect non-green matrix job results.

Closes: molecule-ai/molecule-sdk-python#11

-- **`run_heartbeat_loop(stop_event)` and `run_agent_loop(stop_event)`** (KI-009):
-  Both loops accept an optional `threading.Event` parameter. When the event is set
-  from another thread, the loop exits immediately with return value `"stopped"`.
-  The check runs before `max_iterations` so a signal always wins. Useful for
-  embedding the client in a long-running process that needs a clean shutdown path:
-  ```python
-  import threading, time
-  from molecule_agent import RemoteAgentClient
-  stop = threading.Event()
-  client = RemoteAgentClient(...)
-  # Signal-safe: call stop.set() from any thread to stop the loop
-  terminal = client.run_heartbeat_loop(stop_event=stop)
-  # terminal == "stopped" if stop.set() was called, else "paused"/"deleted"
-  ```
