Byungsker 17578d77e1 fix(agents): add forward-compat fallback for google-gemini-cli gemini-3.1-pro/flash-preview (#26570)
* fix(agents): add "google" provider to isReasoningTagProvider to prevent reasoning leak

The gemini-api-key auth flow creates a profile with provider "google"
(e.g. google/gemini-3-pro-preview), but isReasoningTagProvider only
matched "google-gemini-cli" (OAuth) and "google-generative-ai". As a
result:
- reasoningTagHint was false → system prompt omitted <think>/<final>
  formatting instructions
- enforceFinalTag was false → <final> tag filtering was skipped

Raw <think> reasoning output was delivered to the end user.

Fix: add the bare "google" provider string to the match list and cover
it with two new test cases (exact match + case-insensitive).

Fixes #26551

* fix(agents): add forward-compat fallback for google-gemini-cli gemini-3.1-pro/flash-preview

gemini-3.1-pro-preview and gemini-3.1-flash-preview are not yet present in
pi-ai's built-in google-gemini-cli model catalog (only gemini-3-pro-preview
and gemini-3-flash-preview are registered). When users configure these models
they get "Unknown model" errors even though Gemini CLI OAuth supports them.

The codebase already has isGemini31Model() in extra-params.ts, which proves
intent to support these models. Add a resolveGoogleGeminiCli31ForwardCompatModel
entry to resolveForwardCompatModel following the same clone-template pattern
used for zai/glm-5 and anthropic 4.6 models.

- gemini-3.1-pro-* clones gemini-3-pro-preview (with reasoning: true)
- gemini-3.1-flash-* clones gemini-3-flash-preview (with reasoning: true)

Also add test helpers and three test cases to model.forward-compat.test.ts.

Fixes #26524

* Changelog: credit Google Gemini provider fallback fixes
