- Add new `openspec change` command with three subcommands
- Implement JSON output capability for change proposals
- Add deprecation warning to legacy `openspec list` command
- Enable --requirements-only filtering for change show
- Support --strict mode and --json flags for validation
This provides programmatic access to change proposals through JSON output
and establishes a consistent resource-based command structure.
The --deltas flag was ambiguous. Since it shows only the requirement
changes (ADDED/MODIFIED/REMOVED/RENAMED sections), rename it to
--requirements-only to be explicit about what it displays.
Add three OpenSpec change proposals for enhancing the CLI:
- add-spec-commands: Resource-based spec commands with JSON output
- add-change-commands: Resource-based change commands with JSON output
- add-zod-validation: Runtime validation with detailed error reporting
These proposals enable programmatic access to specs and changes,
improving integration with CI/CD pipelines and external tooling.
