feat: add processor state machine and alert mechanism

- Add ProcessorJobStatus enum (8 states: Idle/Waiting/Ready/Pending/Running/Completed/Failed/Skipped)
- Add processor_alerts table (migrations/034)
- Add emit_processor_alert() to redis_client.rs
- Add ConditionResult enum + check_dependencies() to job_worker.rs
