fix: watchdog health check test expects 5 checks not 4 (#1512)

The test_returns_report_with_all_checks expected 4 checks but
run_health_checks() returns 5 (including Kimi Heartbeat).

Fixed:
- Updated docstring: "all four checks" → "all five checks"
- Updated assertion: len(report.checks) == 5
- Added "Kimi Heartbeat" to expected check names

Closes #1512
