chore: register sys_migration after merging main (#3583)

Merging main brought in the ADR-0104 deployment-migration gate, whose
`sys_migration` object the platform-object registry did not list — and
the conformance ratchet failed exactly as intended, which is the point
of having it rather than a prefix heuristic.

Also regenerates the api-surface snapshot for the union of main's new
exports and this branch's.

Re-verified on the merged base: lint 390, spec 6681, cli 637 passing;
eslint, nul-bytes, api-surface clean; and the three example apps
(app-crm, app-showcase, app-todo) still produce zero findings.
