Re-enable cronTool service integration after completing the ToolResult
refactor (US-016). Removed all temporary disable comments and restored
full cron service lifecycle including start/stop operations.
Additional improvements:
- Add thread-safe access to onHeartbeatWithTools handler
- Fix channel parsing to handle user IDs with special characters
- Add error handling for state file loading failures
Remove .ralph/ directory files from git tracking.
These are no longer needed as the tool-result-refactor is complete.
Also removes root-level prd.json and progress.txt.
