- Changed Press Release topic source from task_name to "PR Topic" custom field
- Added required_fields config to skill_map so scheduler validates before
setting task to "automation underway"
- Tasks missing PR Topic, Customer, or IMSURL are silently skipped with
a notification and re-checked on next poll
- Updated docs and CLAUDE.md with new field mapping
