feat(catalog): updated model catalog configurations and pricing

- Added configurations for `anthropic/claude-sonnet-5` under openrouter, vercel-ai-gateway, and zenmux providers.
- Reduced model pricing and cost structure rates for `anthropic/claude-sonnet-5`.
- Removed `trustExplicitThinkingOnly` compatibility flag from several Claude and Gemini model entries.
- Removed legacy `disableStrictTools` property from model definitions and updated tests.
- Fixed model builder variant collapse logic to properly map `compatConfig` to `compat`.
- Sanitized environment variables in git-clone test helpers to avoid host-leakage in test runs.
