Add CloudWatch alarms, Secrets Manager integration, Lambda concurrency limits, env-var scoping, and lambda trigger type to CHANGELOG, README, and Hugo docs (terraform, alerting, aws architecture). Add 6 missing event types to alerting reference. Fix stale "Build 4 Lambda handlers" count.
TriggerCondition gains a Deadline field (":MM" or "HH:MM") controlling
when the auto-trigger window closes for sensor-triggered pipelines.
New EventSensorDeadlineExpired event type for observability.
Uses DynamoDB ConditionExpression attribute_not_exists(PK) to prevent overwriting a trigger row that was acquired between the read and write.
Remove cron-only SLA guard so sensor-triggered pipelines get proactive SLA scheduling. Add checkTriggerDeadlines scan that writes FAILED_FINAL and publishes SENSOR_DEADLINE_EXPIRED when the trigger window expires without the pipeline starting. Manual restart via RERUN_REQUEST still works. Includes 5 tests covering hourly/daily deadlines, skip-if-exists, and not-yet-expired scenarios.
