fix: improve VS Code config sync reliability and TOML parsing

- Support both single and double quotes in TOML base_url parsing
- Fix regex capture group index for consistent parsing
- Improve "applied" status detection by comparing normalized URLs
- Add validation to prevent empty base_url writes for non-official providers
- Enhance error handling with user-friendly notifications
