fix: lite schema validation

[sanny-io]

Fixes #2793 and #2764

Adds a new @@@lite attribute, which specifies that an attribute should not be stripped when generating lite schemas. All validation attributes, @meta, and @@meta, are decorated with it.

@default and @updatedAt are also decorated with because the frontend hooks rely on checking them.

The Zod factory test suite now runs against both a full schema and a lite schema.

📝 Walkthrough

Walkthrough

Lite-compatible attributes now carry @@@lite markers. Lite schema generation filters attributes by those markers. CLI and Zod tests cover filtered output and full and lite schema targets.

Changes

Lite schema attribute preservation

Layer / File(s)	Summary
Define lite-compatible attributes packages/language/res/stdlib.zmodel, packages/language/src/utils.ts	Standard validation, metadata, default, and timestamp attributes now carry @@@lite. isLiteAttribute identifies marked attributes.
Filter generated lite schema attributes packages/sdk/src/ts-schema-generator.ts	Lite generation filters model, type-definition, and field attributes by isLiteAttribute. Non-lite generation remains unchanged.
Validate filtered schema output packages/cli/test/ts-schema-gen.test.ts	Tests verify removal of incompatible attributes and preservation of compatible attributes on models, fields, and type definitions.
Generate and run the lite Zod schema packages/zod/package.json, packages/zod/tsconfig.json, packages/zod/vitest.config.ts, packages/zod/test/factory.test.ts, packages/zod/test/schema/schema-lite.ts	The Zod package generates a lite schema and runs separate full and lite Vitest projects. The test factory selects the schema based on ZENSTACK_TEST_SCHEMA_TARGET.
