**refactor(mcpService): use enum for MCP request type**

### Changes:
- **mcpService.ts**:
  - Updated `type` in `/mcp/tools` route to use `MCPRequestType.SYSTEM_INFO` enum instead of hardcoded string `'SYSTEM_INFO'`.
  - Removed redundant `infoType: 'availableTools'` from the MCP request payload.
  - Added `MCPRequestType` import from `@soulcraft/brainy`.

### Purpose:
Replaced hardcoded request type string with an enum for improved type safety and maintainability. Removed unnecessary `infoType` parameter, aligning the request payload with updated requirements.
