Add `extra_headers` config field and `ZEROCLAW_EXTRA_HEADERS` env var support so users can specify custom HTTP headers for provider API requests. This enables connecting to providers that require specific headers (e.g., User-Agent, HTTP-Referer, X-Title) without a reverse proxy. Config file headers serve as the base; env var headers override them. Format: `Key:Value,Key2:Value2` Closes #3189 Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> Co-authored-by: Argenis <theonlyhennygod@gmail.com>
