• refactor(executor): dedupe thinking metadata helpers across Gemini executors

  Extract applyThinkingMetadata and applyThinkingMetadataCLI helpers to
  payload_helpers.go and use them across all four Gemini-based executors:
  - gemini_executor.go (Execute, ExecuteStream, CountTokens)
  - gemini_cli_executor.go (Execute, ExecuteStream, CountTokens)
  - aistudio_executor.go (translateRequest)
  - antigravity_executor.go (Execute, ExecuteStream)
  
  This eliminates code duplication introduced in the -reasoning suffix PR
  and centralizes the thinking config application logic.
  
  Net reduction: 28 lines of code.

• **feat(util): add -reasoning suffix support for Gemini models**

  Adds support for the `-reasoning` model name suffix which enables
  thinking/reasoning mode with dynamic budget. This allows clients to
  request reasoning-enabled inference using model names like
  `gemini-2.5-flash-reasoning` without explicit configuration.
  
  The suffix is normalized to the base model (e.g., gemini-2.5-flash)
  with thinkingBudget=-1 (dynamic) and include_thoughts=true.
  
  Follows the existing pattern established by -nothinking and
  -thinking-N suffixes.

• feat(claude): add thinking model variants and beta headers support

  - Add Claude thinking model definitions (sonnet-4-5-thinking, opus-4-5-thinking variants)
  - Add Thinking support for antigravity models with -thinking suffix
  - Add injectThinkingConfig() for automatic thinking budget based on model suffix
  - Add resolveUpstreamModel() mappings for thinking variants to actual Claude models
  - Add extractAndRemoveBetas() to convert betas array to anthropic-beta header
  - Update applyClaudeHeaders() to merge custom betas from request body
  
  Closes #324

• **chore(executor): update default agent version and simplify const formatting**

  - Updated `defaultAntigravityAgent` to version `1.11.5`.
  - Adjusted const value formatting for improved readability.
  
  **feat(executor): introduce fallback mechanism for Antigravity base URLs**
  
  - Added retry logic with fallback order for Antigravity base URLs to handle request errors and rate limits.
  - Refactored base URL handling with `antigravityBaseURLFallbackOrder` and related utilities.
  - Enhanced error handling in non-streaming and streaming requests with retry support and improved metadata reporting.
  - Updated `buildRequest` to support dynamic base URL assignment.

• **feat(executor, translator): enhance token handling and payload processing**

  - Improved Antigravity executor to handle `thinkingConfig` adjustments and default `thinkingBudget` when `thinkingLevel` is removed.
  - Updated translator response handling to set default values for output token counts when specific token data is missing.

• **feat(executor): add model alias mapping and improve Antigravity payload handling**

  - Introduced `modelName2Alias` and `alias2ModelName` functions for mapping between model names and aliases.
  - Improved Antigravity payload transformation to include alias-to-model name conversion.
  - Enhanced processing for Claude Sonnet models to adjust template parameters based on schema presence.

• **feat(translator): add Antigravity translation logic**

  - Introduced request and response translation functions to enable compatibility between OpenAI Chat Completions API and Antigravity.
  - Registered translation utilities for both streaming and non-streaming scenarios.
  - Added support for reasoning content, tool calls, and metadata handling.
  - Established request normalization and embedding for Antigravity-compatible payloads.
  - Added new fields to `Params` struct for better tracking of finish reasons, usage metadata, and tool usage.
  - Refactored handling of response transitions, final events, and state-driven logic in `ConvertAntigravityResponseToClaude`.
  - Introduced `appendFinalEvents` and `resolveStopReason` helper functions for cleaner separation of concerns.
  - Added `TotalTokenCount` field to `Params` struct for enhanced token tracking.
  - Updated token count calculations to fallback on `TotalTokenCount` when specific counts are missing.
  - Introduced `hasNonZeroUsageMetadata` function to validate presence of token data in `usage_metadata`.

• **feat(auth, executor, cmd): add Antigravity provider integration**

  - Implemented OAuth login flow for the Antigravity provider in `auth/antigravity.go`.
  - Added `AntigravityExecutor` for handling requests and streaming via Antigravity APIs.
  - Created `antigravity_login.go` command for triggering Antigravity authentication.
  - Introduced OpenAI-to-Antigravity translation logic in `translator/antigravity/openai/chat-completions`.
  
  **refactor(translator, executor): update Gemini CLI response translation and add Antigravity payload customization**
  
  - Renamed Gemini CLI translation methods to align with response handling (`ConvertGeminiCliResponseToGemini` and `ConvertGeminiCliResponseToGeminiNonStream`).
  - Updated `init.go` to reflect these method changes.
  - Introduced `geminiToAntigravity` function to embed metadata (`model`, `userAgent`, `project`, etc.) into Antigravity payloads.
  - Added random project, request, and session ID generators for enhanced tracking.
  - Streamlined `buildRequest` to use `geminiToAntigravity` transformation before request execution.
