feat: weekly progress update system for TurboQuant (#76)

- scripts/weekly_update.py: Auto-generates weekly update from git log,
  Gitea API (issues/PRs/blockers), and benchmark results. Supports
  --post to issue #76, --json for raw data, --since for date range.
- scripts/weekly_update.sh: Shell wrapper for convenience.
- docs/WEEKLY_TEMPLATE.md: Manual update template.
- docs/PROJECT_STATUS.md: Added Weekly Progress Updates section with
  process (weekly cadence, benchmark-as-happens, blocker escalation).
- tests/test_weekly_update.py: Validates script runs, JSON output,
  and handles edge cases.

+TurboQuant Weekly Progress Update Generator
+
+Generates a structured weekly update from:
+- Git log (commits since last week)
+- Open/closed issues and PRs
+- Benchmark results
+- Blockers (open issues labeled 'blocker')
+
+Usage:
+    python3 scripts/weekly_update.py                    # This week
+    python3 scripts/weekly_update.py --since 2026-04-08 # Custom range
+    python3 scripts/weekly_update.py --post             # Post as Gitea comment on tracking issue
