Refactor Zod schemas and constants for ObjectStack

- Moved Zod schemas related to objects, permissions, validation, views, and workflows from `packages/spec/src/zod/meta` to `packages/spec/src/data`.
- Introduced new Zod schemas for field definitions and constants for package structure in `packages/spec/src/system/constants`.
- Added manifest schema for ObjectStack packages and defined plugin runtime interfaces.
- Created UI schemas for actions, applications, dashboards, and views.
- Ensured all schemas are properly typed and documented for better maintainability and clarity.
