feat(10.8): add Progress Tracker — track test/doc coverage, issue close rate, dep freshness

Implements 10.8: Progress Tracker.

- Script: scripts/progress_tracker.py
- Stores weekly snapshots in metrics/snapshots/ (auto-created)
- Generates trends table in metrics/TRENDS.md
- Tracks: test-to-source ratio, doc coverage via AST, issue close rate (Gitea API), dep freshness (pip)
- Outputs stdout summary for weekly review

Usage:
    python3 scripts/progress_tracker.py
    python3 scripts/progress_tracker.py --json
    python3 scripts/progress_tracker.py --output metrics/TRENDS.md

Weekly cron: 0 9 * * 1 cd /path && python3 scripts/progress_tracker.py

Closes #173
