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

+Progress Tracker — Pipeline 10.8
+Track improvement metrics over time. Are we getting better?
+
+Metrics tracked:
+ 1. Test coverage  — % of Python functions with associated tests (test:source file ratio + line coverage if available)
+ 2. Doc coverage   — % of Python callables with docstrings (AST-based)
+ 3. Issue close rate — closed / (opened + closed) per week (Gitea API)
+ 4. Dep freshness  — % of requirements pinned vs outdated (pip list --outdated)
+
+Output:
+ - metrics/snapshots/YYYY-MM-DD.json  — one snapshot per run
+ - metrics/TRENDS.md                  — cumulative markdown table
+ - stdout summary
+
+Usage:
+    python3 scripts/progress_tracker.py
+    python3 scripts/progress_tracker.py --json
+    python3 scripts/progress_tracker.py --output metrics/TRENDS.md
