review: review PR #20 and add gitignore for cache artifacts

[google-labs-jules]

Reviewed Pull Request #20 (origin/dogfood/crush-mcp-negative-verification).

Review Summary for PR #20

• Title / Scope: Make negative-path mode explicit to Crush
• Branch: origin/dogfood/crush-mcp-negative-verification
• Key Changes:
  1. Fixed enum value in scripts/dogfood-crush-mcp-real.py: changed WorkerStatus.FAILURE to WorkerStatus.FAILED.
  2. Added --expect-failure command-line flag to scripts/dogfood-crush-mcp-real.py to enable deliberate verification failure mode.
  3. Added force_failure parameter and handling in VerificationWorker when --expect-failure is active.
  4. Updated agent prompt instructions dynamically based on whether --expect-failure is specified.
  5. Updated harness assertions and output messages to expect status 'failed' rather than 'success' during deliberate negative-path qualification runs.
• Verdict: LGTM. The changes properly fix a bug with WorkerStatus and cleanly implement explicit negative-path verification for Crush dogfood qualification. Added .gitignore to prevent Python bytecode/cache artifacts from dirtying git status.
