Add real-time merge preview functionality to all config editor components
(Claude, Codex, Gemini) that shows the final merged configuration when
common config is enabled.
UI changes:
- Add finalConfig/finalEnv prop to display merged result
- Add toggle button to show/hide merge preview (Eye/EyeOff icons)
- Auto-show preview when common config is enabled
- Display custom config editor with label when preview is visible
- Show read-only merged preview below custom config
- Add visual indicators: "只读" badge, green hint text
The preview helps users understand how their custom configuration
combines with the shared common config template before saving.
- Add backend command to extract common config snippet from current provider
- Automatically extract common config on first run after importing default provider
- Auto-enable common config checkbox in new provider mode when snippet exists
- Refactor Gemini common config to operate on .env instead of config.json
- Add "Extract from Current" button to all three common config modals
- Update i18n translations for new extraction feature
- Add new AiHubMix provider preset with dual endpoints
- Fix AnyRouter base_url inconsistency (add /v1 suffix)
- Add configuration wizard shortcut link for Codex custom mode
- Improve accessibility with aria-label for wizard button
- Remove unused isCustomMode prop from CodexConfigEditor
- Add internationalization for new UI elements (zh/en)
- Migrate all form components from ProviderForm/ to providers/forms/
- Create shared components to eliminate code duplication:
* ApiKeySection: unified API key input with "Get API Key" link
* EndpointField: unified endpoint URL input with manage button
- Refactor ClaudeFormFields (-31% lines) and CodexFormFields (-33% lines)
- Update all import paths to use new locations
- Reduce code duplication from ~12% to ~7%
This change improves maintainability and makes the codebase more DRY.
