* feat(cli,domain): support non-global namespace skill download
Parse namespace from skill name using -- separator (e.g.,
astroclaw--api-gateway) so users don't need --namespace flag.
Allow anonymous download for any PUBLIC skill regardless of namespace.
CLI changes:
- Add cli/src/shared/skill-name-parser.ts utility
- Update install and remove commands to parse skill name argument
- 10 unit tests covering edge cases
Domain changes:
- SkillDownloadService.isAnonymousDownloadAllowed: drop namespace
type check, only require PUBLIC visibility
- Update test to expect success for team-namespace public skill
Synced from SAAS commit 26c67e31b1221249cf9b73321d1b726d8ba6e6df
* fix(cli): use bun:test instead of vitest in skill-name-parser test
Add 36 test cases covering:
- Path traversal and symlink attack prevention in archive extraction
- SkillHubClient error handling (401/403/404/network) for all endpoints
- Inventory store concurrent writes and stale lock recovery
- Config store read/write round-trip
- Platform utilities (package-manager, updater, paths)
- Output formatting (printResult, humanize)
Tests use cross-platform commands (node) instead of shell builtins
for CI compatibility across macOS/Linux/Windows.
