Automatically attach OpenRouter app attribution headers (HTTP-Referer, X-OpenRouter-Title, X-OpenRouter-Categories) whenever a provider's base_url points at openrouter.ai, so Codex Warp usage appears in OpenRouter's public rankings and analytics. - Inject attribution in apply_headers_with_accept (src/http.rs), covering chat completions, native /responses, and /models - User-set [providers.<id>.headers] override the automatic values - Add configs/openrouter.toml profile and document in README - Add unit tests in src/http_tests.rs

- Detect OpenRouter by the parsed host (== openrouter.ai or a *.openrouter.ai subdomain) instead of a raw substring match, so look-alike hosts (e.g. openrouter.ai.attacker.example) are no longer misidentified as OpenRouter. - Add tests for case-insensitive host, subdomain, look-alike false-positive, X-Title alias suppression, X-OpenRouter-Categories override, and /responses + /models paths; assert exactly one value per header to catch duplicate-header regressions. - Document the opt-out/override and update detection wording in the README and configs/openrouter.toml. - Use a mut request parameter and add a rationale comment for the hardcoded identity values. Validated: cargo fmt --check, cargo build --locked, cargo test --locked (134 passing).
