Add two tools from the March 23 operational briefing:
- src/infrastructure/claude_quota.py: SQLite-backed tracker for Claude API
usage (tokens, cost, calls) per day/month. Exposes current_mode() which
returns BURST / ACTIVE / RESTING based on daily spend thresholds, enabling
the orchestrator to route inference requests according to the metabolic
protocol (issue #972).
- scripts/claude_quota_check.sh: CLI wrapper with --mode (print mode only)
and --json (machine-readable) flags for quick quota inspection from the
shell or CI scripts.
- tests/infrastructure/test_claude_quota.py: 19 unit tests covering cost
calculation, mode thresholds, store CRUD, and convenience functions.
