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.
