Update CLI lint schema to v1.2 (v0.5 schema blocks v1.x docs) #65
Description
Problem
The CLI lint command uses omniscript-core/cli/schema/osf.schema.json, which is still v0.5. This causes osf lint to fail valid v1.x documents (chart/diagram/code/table/include).
Evidence
- omniscript-core/cli/src/commands/lint.ts loads schema from cli/schema/osf.schema.json.
- Spec is now v1.2 (omniscript-core/spec/v1.2/README.md).
Expected
- Update schema to v1.2 (or align to current stable spec).
- Ensure CLI lint passes valid v1.x documents.
- Update/extend lint tests accordingly.
Acceptance Criteria
- Schema includes v1.0/v1.1/v1.2 blocks and directives.
- osf lint works on v1.x examples without false errors.
- Tests updated for new schema coverage.
