Implement (deprecated)

Superseded by build. implement built a spec or a set of tickets in one session — TDD at pre-agreed seams, a regular typecheck, then a review before committing — leaving the window discipline and the review to judgement. build takes the ticket's contract as its input, runs it as a sequential loop of fresh-child units, gates each unit on crucible and ends at the pull request, so both are structural rather than advisory.

Run /build <ticket-ref> instead.
