Brings module.yaml in line with F∆I 0.12.0's capability naming
convention. The legacy schema_version 1 (with implicit provider)
still loads in 0.12.0 via the grace-period default, but this
bump makes the publisher identity explicit and unblocks
storage-layout migration via 'fai migrate'.
See fai/platform docs/reference/capability-namespaces.yaml +
docs/operations/migration-to-0.12.md.
