fix(channel): remove HEARTBEAT.md from channel system prompt

Browse source 
HEARTBEAT.md is only relevant to the heartbeat worker, which reads it
directly from disk. Including it in channel system prompts caused LLMs
to emit spurious 'HEARTBEAT_OK' acknowledgments at the start of
channel responses.

The agent prompt (src/agent/prompt.rs) still includes HEARTBEAT.md,
which is correct for agent and heartbeat contexts.
