fix(harness): diff-based critic, post-impl checks, edit metrics, realistic targets

- Critic now reviews git diff (12KB) instead of 400 chars of codex CLI headers
- Post-implementation lint + test verification fed to critic
- Edit metrics parsed from git diff hunks (was hardcoded to 0)
- Context tokens estimated from diff length
- Total latency P95 target: 60s → 300s (realistic for codex exec)
- Added single-iteration latency P95 target (150s)
- Pre-publish script gates on BENCH=1 benchmarks + feedback loops
- publish-local.js now runs full quality checks before publishing
