Migrate graphify into a Capability that owns its `graphify` command family,
dispatched via the registry (#961 mechanism) instead of a hardcoded case.
graphify is now an enable/disable plug-in.
- src/graphify-command-router.cts: routeGraphifyCommand (standard route*Command),
reproduces the removed case EXACTLY (query +--budget, status, diff, build,
hidden build snapshot, usage/unknown errors); injectable _graphify test seam.
- capabilities/graphify/capability.json: role feature, tier:full, skills:[graphify],
config:{graphify.enabled default false}, commands:[{family:graphify, module,
router:routeGraphifyCommand}].
- removed case 'graphify' from gsd-tools.cjs; graphify now flows
default -> dispatchCapabilityCommand -> commandFamilies.graphify -> router.
- regenerated registry (commandFamilies/bySkill/configSchema/profileMembership/
capabilityClusters for graphify); tier:full keeps 4c install/surface a no-op.
Equivalence-proven: 8 recording-mock unit tests assert the exact fn+args per
subcommand (budget, snapshot-vs-build); 9 subprocess tests assert distinguishing
output shapes; existing graphify tests pass unchanged through the new path.
Surfaced (not silently accepted): the pre-existing --budget-no-value NaN no-op
quirk, preserved for equivalence, filed separately.
Closes#972
