docs(sdk): document stop_event parameter in CLAUDE.md, README, and __init__

Resolves the post-launch CLAUDE.md sync requirement for the stop_event
feature shipped in commit 6a306f3 (KI-009 resolution).

Changes:
- CLAUDE.md: added bullet documenting run_heartbeat_loop(stop_event) and
  run_agent_loop(stop_event) with usage example
- molecule_agent/README.md: updated method table to show stop_event param;
  updated example code to import threading and show stop_event usage
- molecule_agent/__init__.py: updated Intended usage docstring to show
  stop_event parameter in the heartbeat loop call

+- **`run_heartbeat_loop(stop_event)` and `run_agent_loop(stop_event)`** (KI-009):

+  ```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)
