Generates an intent card skeleton for each named context, bound to its current public surface (so a fresh card is born non-drifted).
$ mix cohere.gen.intent deals billing
$ mix cohere.gen.intent --all # every context-ful group
$ mix cohere.gen.intent deals --force # overwrite an existing card
Cards are the authored layer — the skeleton is scaffolding, not content. Fill in only what cannot be derived: purpose, invariants, decisions, non-goals. If a section has nothing durable to say, leave it empty rather than restating the code.
