test(llm): re-record golden scenarios against live providers

Verifies the new Usage mapper code against live provider responses for OpenAI Chat, OpenAI Responses, Anthropic, Gemini, DeepSeek, and TogetherAI — 16 fresh recordings, all assertions pass. No existing cassettes were modified; these populate test slots that were previously skipped in replay mode. Recorded via: set -a; source .env.recorded.local; set +a RECORD=true bun test test/provider/*.recorded.test.ts Redactor stripped all auth headers; no secrets in the cassettes.
