chore(spec): refresh the public API-surface snapshot for the new exports

The snapshot gate diffs the built export surface against the committed file so
a removed or renamed export cannot silently break a pinned consumer. This
change adds six exports and removes none:

  RAW_FILE_VALUES_CONTEXT_KEY, DATA_MIGRATION_FLAG_OBJECT,
  FILE_REFERENCES_MIGRATION_ID, DataMigrationFlagSchema, DataMigrationFlag,
  isDataMigrationFlagVerified

Ran every gate in the type-check job locally this time — the spec's ten
check:* scripts, the example-app and downstream-contract typechecks — rather
than fixing them one CI round at a time.
