Address review comments: fix paths, cleanup gating, align docs, add tests

[Copilot]

Addresses 9 review comments from PR #2 covering path handling, service instantiation, cleanup logic, documentation alignment, and test coverage.

Code Changes

Path handling - Anchored log_dir and report_dir to project root via Path(__file__).resolve().parent.parent instead of relative paths. Prevents writes to unexpected locations when run from cron or outside repo root.

Service cleanup - Removed unused MetricsService and LoggingService instantiations. These start background asyncio tasks that run unexpectedly during one-shot audit and produce noisy cancellation logs.

Database cleanup gating - Changed from unconditional cleanup on any health issue to gated execution:

# Before: runs for any health check failure
if diagnosis['issue']['type'] == 'health_check':
    results = await run_database_cleanup()

# After: only runs when DB components specifically unhealthy
if diagnosis['issue']['type'] == 'health_check':
    unhealthy_components = diagnosis['issue'].get('components', [])
    db_components = [c for c in unhealthy_components if 'database' in c.lower() or 'db' in c.lower()]
    if db_components:
        results = await run_database_cleanup()

Prevents destructive cleanup operations when external services fail.

Threshold alignment - Updated docstring and filter logic documentation from > 400 to >= 400 to match actual implementation. Changed AGENTS.md from "24-hour window" to "complete log scan" to reflect actual behavior.

Advisory labeling - Prefixed automated recommendation actions with [ADVISORY] marker to distinguish from truly automated operations like DB cleanup.

Documentation Changes

AGENTS.md clarifications:

• Added "Internal Monitoring Tool (Not Part of Core YouTube-Link Workflow)" header to reconcile with documented product workflow
• Rewrote "Ruthless Solutions" section to distinguish pre-approved automated actions (log analysis, report generation, safe DB cleanup) from advisory-only recommendations (structural rewrites, schema changes, record repairs)
• Added implementation note explaining current automation scope

Test Coverage

Added 22 unit tests covering:

• Path anchoring and absolute path validation
• Status code filtering (>= 400 threshold, 200/400/500 cases)
• Database cleanup gating (HTTP errors don't trigger, non-DB health issues don't trigger, DB-specific health issues do trigger)
• Dry-run mode (verifies no mutations, [DRY RUN] markers present)
• Advisory labeling (restart/review/optimize actions tagged [ADVISORY])

All tests passing. CodeQL clean.
