Add schema validation to the `json-cas put` command to ensure data
integrity. The CLI now validates the payload against the specified
schema before storing, and exits with a non-zero code and descriptive
error message if validation fails.
Changes:
- Add schema existence check in cmdPut()
- Add payload validation before storing
- Exit with error code 1 on validation failure
- Provide helpful error messages indicating the file and schema
- Add comprehensive test suite with 16 test scenarios covering:
- Valid data (regression tests)
- Type mismatches (new validation)
- Schema errors (edge cases)
- Integration with existing features
- Error message quality
The hash command continues to work without validation (dry-run
consistency), and schema put continues to use its own validation.
