Self-describing timestamp types for LLM-friendly output.
- New
Timestamp(Unix seconds) andTimestampMilli(Unix ms): marshal to RFC3339 (local TZ), unmarshal from epoch-or-RFC3339, zero→0 sentinel. - Response time fields migrated to these types; request/input fields and durations/offsets stay int64.
- BREAKING (pre-1.0):
CreateIncident/CreateStatusIncidentnow return typed*CreateIncidentOutput/*CreateStatusIncidentOutputinstead ofany; several response field types changed int64→Timestamp. - Added CLAUDE.md + AGENTS.md.
