Upgrade CLI to v0.2.0: add validate, list commands, --version, --dry-run, --backup flags

- Fix npm test glob pattern for Node >= 21 compatibility
- Add --version/-v flag to display package version
- Add validate command: run 78 profile checks (files, skills, frontmatter, legacy patterns, AGENTS mapping)
- Add list command: display all 13 bundled skills with descriptions
- Add --dry-run/-n flag for init: preview files without copying
- Add --backup/-b flag for init --force: backup existing .agent before overwrite
- Add name field to workflow frontmatter (brainstorm, execute-plan, write-plan)
- Expand smoke check to cover all 13 skills and new command files
- Increase test coverage from 3 to 20 tests (cli, init, validate)
