- main.py: drops the hard-coded McpService class and MCP_SERVICES list.
Lifespan now calls discover_and_filter() which does import + env
filtering. Unset MCP_SERVICES reproduces today's behavior exactly.
- spark_executor/service.py: new file exporting SERVICE = McpService(
name='spark_executor', app=spark_executor.app, mount_path='/spark-executor-mcp').
- files_mcp/service.py: new file exporting SERVICE = McpService(
name='files', app=files_mcp.app, mount_path='/files-mcp').
The McpService dataclass itself moved to common/mcp_service.py in the
prior commit. 327 existing tests pass unchanged.
