Fix truncated files, implement TODOs, remove all compilation errors and warnings

- Complete truncated auto_task.rs, autotask_api.rs, intent_compiler.rs, mcp_client.rs, safety_layer.rs
- Add missing structs: RiskFactor, ResourceUsage, TaskError, RollbackState, TaskSchedule, HealthStatus
- Add missing IntentCompiler methods: call_llm, assess_risks, estimate_resources, check_ambiguity, store_compiled_intent
- Implement SET ATTENDANT STATUS database storage
- Implement queue position calculation in transfer_to_human
- Add llm_tokens to ResourceEstimate
- Fix all unused imports and variables
- Add proper derives (Copy, PartialOrd) where needed
