* fix: use change-id as fallback title instead of "Untitled Change"
Fixes#225 by addressing mismatch between proposal template and title extraction:
- Updated proposal template to include `# Change: [description]` header
- Changed extractTitle fallback from "Untitled Change" to change-id
- Updated all extractTitle call sites to pass changeName parameter
This ensures both new and existing proposals display meaningful titles.
* refactor: make title extraction case-insensitive for "Change:"
Makes the extractTitle regex case-insensitive to handle variations like
"# change:" or "# CHANGE:" in addition to "# Change:".
- Replace any types with proper Change and Delta types from schemas
- Add error logging in catch blocks when DEBUG env var is set
- Include file paths in error messages for better debugging
- Extract regex patterns and magic strings as constants
- Improve code maintainability and type safety
- 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.
Implements new `openspec spec` command with three subcommands:
- `spec show`: Display specs with JSON output and filtering options
- `spec list`: List all available specifications
- `spec validate`: Validate spec structure with detailed reporting
Key features:
- JSON output for CI/CD integration (--json flag)
- Content filtering (--requirements, --no-scenarios, -r)
- Strict validation mode (--strict)
- Support for both Overview/Purpose and Requirements/Behavior sections
This enables programmatic access to OpenSpec specifications for external
tools and automated pipelines as specified in the add-spec-commands change.
