Development record

The glossary term .abcd/development/brief/glossary/core/intent.md says an intent is frozen at promotion time, an immutable input artefact never edited after /abcd:intent plan is run (lines 20-21), but shipped sub-verbs edit planned intents: abcd intent target writes a planned intent's target_release line, intent edge writes its blocked_by and builds_on lists, intent hold writes a held line on a draft or planned intent, intent plan on a planned intent stamps its scope conditions, and intent interview runs on a planned intent and edits its record.
