Various SDK improvements (#18115)

## Summary

- **Refactor frontend metadata loading architecture**: Split the
monolithic `EagerMetadataLoadEffect` into focused provider effects
(`UserMetadataProviderEffect`, `ObjectMetadataProviderEffect`,
`ViewMetadataProviderEffect`) orchestrated by `MetadataProviderEffects`.
Replaced `UserProvider` + `ObjectMetadataItemsProvider` with a single
`MetadataGater` that gates rendering on `isAppMetadataReadyState`. The
metadata store now validates view-object consistency before promoting
views, and `updateDraft` skips no-op updates via deep equality checks.

- **SDK CLI improvements**: Added `app:typecheck` command, improved
error handling in API sync (extracts GraphQL error messages), added
`serializeError` utility for human-readable error output, added `error`
file status to dev mode orchestrator with UI support, and fixed
ClickHouse migration/seed commands to use `transpile-only`.
