Ali Khokhar 0b86dd4ef8 Add GitHub Models provider (#989) ... ## Problem FCC does not expose GitHub Models, so users with GitHub Models access cannot route Claude, Codex, or messaging prompts through GitHub's hosted model catalog. ## Changes | Before | After | | --- | --- | | Provider catalog did not include GitHub Models. | Provider catalog includes `github_models` with token, proxy, admin, smoke, and model picker wiring. | | Requests could not target GitHub Models inference. | `providers/github_models` routes OpenAI-chat requests to `https://models.github.ai/inference`. | | Model discovery assumed provider `/models` compatibility. | GitHub Models discovery uses the catalog API and advertises stream/tool-capable models. | | OpenAI-chat transport could not set provider default headers. | OpenAI-chat transport accepts provider-owned default headers. | | Docs and templates omitted GitHub Models setup. | README, `.env.example`, and architecture docs document GitHub Models setup and ownership. | <!-- greptile_comment --> <details open><summary><h3>Greptile Summary</h3></summary> This PR adds GitHub Models as a new provider. The main changes are: - New `github_models` provider runtime, catalog, settings, and admin wiring. - OpenAI-chat transport support for provider-owned default headers. - GitHub Models catalog discovery filtered to streaming and tool-capable models. - Smoke configuration, environment template, docs, and tests for the new provider. - Package version and lockfile updates for the new feature. </details> <h3>Confidence Score: 5/5</h3> Safe to merge with low risk. The provider is wired through runtime creation, catalog metadata, settings, admin fields, smoke config, docs, version metadata, and focused tests. No blocking correctness or security issues were found in the changed paths. No files require special attention. <details><summary><h3><a href="https://www.greptile.com/trex"><img alt="T-Rex" src="https://greptile-static-assets.s3.amazonaws.com/trex/trex_green.svg" height="20" align="absmiddle"></a> T-Rex Logs</h3></summary> **What T-Rex did** - Before-change focused pytest run against HEAD^ showed no GitHub Models provider tests were collected. - After-change focused pytest run showed all 37 provider/runtime tests passed. - After-change harness output captured structured evidence for catalog discovery and OpenAI-chat request routing, and the harness exited successfully. - A temporary harness Python script was generated to capture the mocked request/response evidence. <a href="https://app.greptile.com/trex/runs/13317138/artifacts"><picture><source
