[codex] fix MCP management lifecycle (#1144)

* feat(mcp): add MCP server management UI

- Server CRUD: add/edit/remove with YAML/JSON Monaco editor
- raw_config passthrough: zero field loss on edit/toggle
- tool_details embedding: single-request card data (1+N → 1)
- Auto-retry exponential backoff (2s→32s, max 5 retries)
- Route safety guards (hasRoute) for dynamic sidebar
- i18n: 9 languages (de/en/es/fr/ja/ko/pt/zh/zh-TW)
- 19 unit tests + 8 UX browser tests
- 35 files, +2933 lines

* fix mcp management lifecycle

+# feat(mcp): Add MCP Server Management UI
+
+## Summary
+
+Add a complete MCP (Model Context Protocol) server management interface that allows users to manage MCP servers through the web UI. This feature provides a user-friendly way to configure, monitor, and control MCP servers without editing configuration files manually.
+
+## Features
+
+### Core Functionality
+- **Server List**: View all configured MCP servers with real-time status indicators (connected/disconnected/disabled)
+- **Add Server**: Add new MCP servers with YAML or JSON configuration editor (Monaco Editor)
+- **Edit Server**: Modify existing server configurations — uses `raw_config` passthrough to avoid field loss
+- **Remove Server**: Delete servers with confirmation dialog to prevent accidental deletion
+- **Enable/Disable**: Toggle individual servers on/off with instant feedback
+- **Test Connection**: Verify server connectivity and list available tools
+- **Reload**: Refresh server configuration without restarting
+- **Search/Filter**: Filter servers by name for quick navigation
+
+### User Experience
+- **Monaco Editor**: Full-featured code editor with YAML/JSON syntax highlighting
+- **Responsive Design**: Works on desktop (1280px), tablet (768px), and mobile (480px)
+- **Auto-Retry**: Exponential backoff (2s → 4s → 8s → 16s → 32s, max 5 retries) for servers that haven't connected yet
+- **Loading States**: Clear feedback during async operations
+- **Error Handling**: User-friendly error messages with actionable guidance
+- **Multi-language Support**: 9 languages (English, Chinese Simplified/Traditional, Japanese, Korean, German, Spanish, French, Portuguese)
+
+### Performance Optimizations
+- **`raw_config` Passthrough**: Backend returns the original config dict as-is — frontend edits/Toggles use it directly, eliminating field-rebuild bugs
+- **`tool_details` Embedding**: `mcp_list` response embeds filtered `{name, description}` per server, reducing first-load from 1+N requests to 1
+- **Route Safety**: `hasRoute()` guards for dynamic sidebar routes to prevent Vue runtime crashes
+
+## Technical Implementation
+
+### Frontend (Vue 3 + Naive UI)
+- `McpManagerView.vue`: Main management component with auto-retry, search, modal management
+- `McpServerCard.vue`: Server card component with status indicators, tool tags, action buttons
+- `mcp.ts` (api): Type definitions (`McpServerInfo` with `raw_config`, `tool_details`) and API client
+- Monaco Editor integration for configuration editing
+- Reactive state management with Vue 3 Composition API
+
+### Backend (Koa + TypeScript)
+- `mcp.ts` (controller): Request handlers with input validation
+- `mcp.ts` (service): Business logic layer with typed interfaces
+- `mcp.ts` (routes): RESTful API endpoints
+- `mcp-types.ts`: Shared type definitions
+- `client.ts` (bridge): AgentBridge client methods
+
+### Python Bridge (`hermes_bridge.py`)
+- `_build_server_entry()`: Normalized server entry builder returning `raw_config` and `tool_details`
+- `_mcp_list()`: Lists all MCP servers with embedded filtered tool details
+- `_mcp_server_add/update/remove`: Full CRUD with config validation and atomic YAML persistence
+- `_mcp_server_toggle`: Enable/disable individual servers
+- `_mcp_server_test`: Connection test with tool discovery
+- `_mcp_reload`: Hot-reload server connections
+- Background MCP discovery on worker startup
+
+### Testing
+- `mcp-controller.test.ts`: 19 unit tests covering all controller methods
+- Tests for success cases, error handling, and edge cases
+- Mock-based testing for isolation

+- [x] No linting errors
+
+## Architecture Decisions
+
+### 1. `raw_config` Passthrough
+**Problem**: Rebuilding config from scattered fields (command, args, env, etc.) caused field loss on edit/Toggle.
+**Solution**: Backend returns `raw_config` (original dict from config.yaml), frontend edits it directly. Zero rebuild, zero field loss.
+
+### 2. `tool_details` Embedding
+**Problem**: First load required 1 API call for server list + N calls for tool details (one per server).
+**Solution**: `mcp_list` response embeds `tool_details` (filtered `{name, description}` per server). Single request for full card data.
+
+### 3. Auto-Retry with Exponential Backoff
+**Problem**: MCP servers may not be connected on first page load (still initializing).
+**Solution**: Auto-retry with exponential backoff (2s, 4s, 8s, 16s, 32s), max 5 retries. Manual refresh resets counter.
+
+### 4. Route Safety Guards
+**Problem**: Unknown routes (e.g., `codingAgents`, `versionPreview`) could crash Vue at runtime.
+**Solution**: `hasRoute()` checks before rendering dynamic sidebar route items.
