  the menu offers exactly what the store will accept, for ANY workflow.

  This replaces the `VALID_TRANSITIONS` shortcut that used to run whenever a workflow's

  below approximates targets from a column's NEIGHBOURS in declared order, which is
  strictly weaker than the graph (in-progress: 4 real targets vs 2 neighbours), so
  deleting it without adjacency would have SHRUNK every default-workflow move menu.

  With adjacency on the wire the shortcut is not merely removable, it is redundant:
  `resolveAllowedColumns(BUILTIN_CODING_WORKFLOW_IR, c)` is byte-identical to
  `VALID_TRANSITIONS[c]` for all six columns, ORDER included — measured, and pinned by
  `@fusion/core`'s `builtin-adjacency-matches-legacy-transitions` test so the
  equivalence cannot drift silently. Custom workflows stop being guessed at.

  relabels moves this change never set out to touch (18 assertion sites across three
