- Server.billing: injected into Config, initialized in main
- handleInvokeFunction: record invocation (TriggerConsole)
- invokeInternalFunction: record invocation (TriggerHTTP)
- handleCreateFunction: record event_type=create
- handleCloneFunction: record event_type=clone
- handleDeleteFunction: record event_type=delete
- table: invocations (namespace, function_name, trigger_type, duration_ms, status_code...)
