feat: 更新 Antigravity 默认模型映射预设

[Bowl42]

User description

Summary

• 同步 Antigravity-Manager 的模型映射配置
• 新增 gpt-4o、o1、o3 系列映射
• 新增具体的 Claude 模式映射
• 更新 gpt-4* 目标为 gemini-3-pro-high

Test plan

⚡ Recommended focus areas for review Logic Change The order of model mappings has changed, which may affect the mapping behavior.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Clarify priority of model mappings Ensure that the mapping for gpt-4o is correctly prioritized over gpt-4. If the intention is to have gpt-4o* take precedence, verify that the order of the rules reflects this priority. Consider adding comments to clarify the intended behavior.** internal/adapter/provider/antigravity/model_mapping.go [22] +{"gpt-4o*", "gemini-3-flash"}, // gpt-4o 系列 (优先于 gpt-4) - Suggestion importance[1-10]: 5 __ Why: The suggestion addresses the importance of order in model mappings, but the existing and improved code are identical, indicating no actual change is proposed.	Low
	Ensure no conflicts in model mappings Verify that the mapping for claude-3-5-sonnet-* does not conflict with other mappings. Ensure that it is correctly prioritized to avoid unintended matches with broader patterns. Consider testing with various inputs to confirm expected behavior. internal/adapter/provider/antigravity/model_mapping.go [29] +{"claude-3-5-sonnet-*", "claude-sonnet-4-5"}, // Claude 3.5 Sonnet - Suggestion importance[1-10]: 5 __ Why: The suggestion highlights the need to verify mapping conflicts, but again, the existing and improved code are the same, showing no modifications are suggested.
