**Title:** Implement Studio MCP Server Tools

**Status:** done

**Dependencies:** 104 ✗, 106 ✓, 107 ✓, 108 ✓

**Priority:** medium

**Description:** Create MCP tools for Claude Monitor to observe traffic, get corrections, switch models, and modify stages.

**Details:**

Extend `src/cli/src/commands/console/inspect-mcp.ts` with studio tools:

```typescript
const studioTools: Tool[] = [
  {
    name: 'get_content_diff',
    description: 'Get original vs transformed vs edited content for a specific event',
    inputSchema: {
      type: 'object',
      properties: {
        eventId: { type: 'string', description: 'Event ID' },
      },
      required: ['eventId'],
    },
  },
  {
    name: 'get_corrections',
    description: 'Get all user corrections (edits) in a session',
    inputSchema: {
      type: 'object',
      properties: {
        sessionId: { type: 'string', description: 'Optional session filter' },
      },
    },
  },
  {
    name: 'get_active_model',
    description: 'Get current proxymodel name and stage list for a project',
    inputSchema: {
      type: 'object',
      properties: {
        project: { type: 'string' },
      },
      required: ['project'],
    },
  },
  {
    name: 'switch_model',
    description: 'Hot-swap the active proxymodel on a project',
    inputSchema: {
      type: 'object',
      properties: {
        project: { type: 'string' },
        model: { type: 'string' },
      },
      required: ['project', 'model'],
    },
  },
  {
    name: 'reload_stages',
    description: 'Force reload all stages from ~/.mcpctl/stages/',
    inputSchema: { type: 'object', properties: {} },
  },
  {
    name: 'get_stage_source',
    description: 'Read the source code of a stage file',
    inputSchema: {
      type: 'object',
      properties: {
        name: { type: 'string' },
      },
      required: ['name'],
    },
  },
  {
    name: 'list_models',
    description: 'List available proxymodels',
    inputSchema: { type: 'object', properties: {} },
  },
  {
    name: 'list_stages',
    description: 'List available stages',
    inputSchema: { type: 'object', properties: {} },
  },
];
```

**Test Strategy:**

Integration test with MCP client: each tool returns expected data format, switch_model actually changes the model, reload_stages picks up file changes, get_corrections returns user edits.
