build: token-monitor v0.1.0 — modular LLM API quota visibility

Implements modular provider probing with two distinct header schemas:
- Teams direct (unified schema): 5h/7d utilization floats, status, reset countdown
- Shelley proxy (classic schema): token/request counts + Exedev-Gateway-Cost (USD/call)
- api-ateam: reports no billing data (confirmed non-existent by recon)

Key: uses claude-haiku-4-5-20251001 for minimal probe calls (1 token).
Rate-limit headers present on ALL responses (200 and 429).

113/113 tests passing.

Built from Face recon (trentuna/a-team#91) — live header capture confirmed
unified schema with utilization floats replaces old per-count schema.
