- feat(codex): Add “Apply to VS Code/Remove from VS Code” button on current Codex provider card

- feat(tauri): Add commands to read/write VS Code settings.json with cross-variant detection (Code/Insiders/VSCodium/OSS)
- fix(vscode): Use top-level keys “chatgpt.apiBase” and “chatgpt.config.preferred_auth_method”
- fix(vscode): Handle empty settings.json (skip deletes, direct write) to avoid “Can not delete in empty document”
- fix(windows): Make atomic writes robust by removing target before rename
- ui(provider-list): Improve error surfacing when applying/removing
- chore(types): Extend window.api typings and tauri-api wrappers for VS Code commands
- deps: Add jsonc-parser
