AMP CLI requests /threads.rss at the root level, but the AMP module
only registered routes under /api/*. This caused a 404 error during
AMP CLI startup.
Add the missing root-level route with the same security middleware
(noCORS, optional localhost restriction) as other management routes.
- Updated `antigravity_openai_request.go` to process non-JSON outputs gracefully by verifying and distinguishing between JSON and plain string formats.
- Ensured proper assignment of parsed or raw response to `functionResponse`.
- Added `ContextLength` field with a value of 200,000 to all applicable Claude model definitions.
- Standardized `MaxCompletionTokens` values across models for consistency and alignment.
**fix(translator): add support for "xhigh" reasoning effort in OpenAI responses**
- Updated handling in `openai_openai-responses_request.go` to include the new "xhigh" reasoning effort level.
Fixes an issue where Claude thinking models would return 400 errors when
the thinking.budget_tokens was greater than or equal to max_tokens.
Changes:
- Add MaxCompletionTokens: 128000 to all Claude thinking model definitions
- Add ensureMaxTokensForThinking() function in claude_executor.go that:
- Checks if thinking is enabled with a budget_tokens value
- Looks up the model's MaxCompletionTokens from the registry
- Ensures max_tokens is set to at least the model's MaxCompletionTokens
- Falls back to budget_tokens + 4000 buffer if registry lookup fails
This ensures Anthropic API constraint (max_tokens > thinking.budget_tokens)
is always satisfied when using extended thinking features.

Closes#324

- Removed unnecessary whitespace in the code.
- Ensured `functionDeclarations` key renaming only occurs if the key exists in Gemini tools processing.
- Prevented unnecessary JSON reassignment when the target key is absent.
- Fixed parameter key renaming to correctly handle `functionDeclarations` and `parametersJsonSchema` in Gemini tools.
- Resolved potential overwriting issue by reassigning JSON strings after each key rename.

Remove generationConfig.maxOutputTokens, generationConfig.responseMimeType and generationConfig.responseJsonSchema from the Gemini payload in translateRequest so we no longer send unsupported or conflicting response configuration fields. This lets the backend or caller control response formatting and output limits and helps prevent potential API errors caused by these keys.
