Expand Shell

Expand a shell into a full implementation plan. The shell's Context, Produces, Consumes, Covers, and high-level Implementation Steps are authoritative. Expansion adds a pattern survey, concrete references, and verification, writes the plan to .turbo/plans/<shell-slug>.md, and deletes the source shell once the plan is in place.

5. Verify the plan against the shell
6. Delete the shell
