fix: add missing showNotice error handling and improve async UI feedback
- Add showNotice error notifications to unlock page async error branches
- Restore showNotice for YAML serialization errors in rules/groups/proxies editor
- Ensure all user-facing async errors are surfaced via showNotice
- Add fade-in animation to layout for smoother theme transition and reduce white screen
- Use requestIdleCallback/setTimeout for heavy UI state updates to avoid UI blocking
- Minor: remove window.showNotice usage, use direct import instead
- Ensure the 'secret' field is present and non-empty during config loading
- Auto-fill with default value if missing to improve compatibility and security
- Update config guard logic for robustness
- Replaced 'http://localhost' and 'http://127.0.0.1' with 'tauri://localhost' and 'http://tauri.localhost' for enhanced compatibility with Tauri development environment.
- Ensures proper CORS configuration for local testing.
- Refactored config guard logic to always inject secure defaults for external-controller-cors (allow-origins: ['http://localhost', 'http://127.0.0.1'], allow-private-network: true).
- Ensures both new and existing user configs are automatically upgraded for enhanced CORS security.
- Improves configuration migration and future maintainability.
fix: add http://localhost:3000 to CORS allow-origins for tauri dev server compatibility
- Only Selector-type groups are available for selection in the group dropdown on the home page node card.
- Node (proxy) selection remains unrestricted.
- Improves user experience and avoids confusion with non-selector groups.
- Remove or disable usage of tauri-plugin-window-state due to compatibility or stability concerns.
- Will revisit and re-enable after further evaluation or upstream fixes.
- When the current group or its 'now' field is missing, fallback to the first proxy in the group's list to ensure a valid active node is always selected.
- When no current group is found, prioritize groups of type 'Selector' for selection, improving compatibility with custom or extended proxy groups.
