Subject: [PATCH] Update Antigravity provider config and headers

- Simplify ANTIGRAVITY_HEADERS to dynamic User-Agent only
- Use IDE_TYPE, PLUGIN_TYPE enums and getPlatformEnum() in metadata
- Update antigravity baseUrl to sandbox endpoint
- Bump User-Agent version from 1.104.0 to 1.107.0
- Remove redundant header spread in AntigravityExecutor
