feat(mcp): add MCP client and configuration support #330

- Introduce `McpClient` with `McpConfig` and `McpServer` data classes.
- Add `mcpServices` property to `AutoDevCustomizeSettings`.
- Include `CustomMCPServersSchemaFileProvider` for MCP schema validation.
- Update UI to support MCP services configuration.
