feat: wire cf_text as openai_compat backend in llm.yaml

Adds the cf-text inference service (circuitforge-core) to the LLM
fallback chain as the first option for cover letter generation.
cf-text now exposes /v1/chat/completions (added in cf-core 69a338b),
making it a drop-in openai_compat backend at port 8006.

CF_TEXT_MODEL and CF_TEXT_PORT added to .env.example. Closes #75.
