Release v1.42.1

[omriariav]

Summary

• Bump the Workspace CLI default version and bundled Claude/Codex plugin manifests to v1.42.1.
• Add v1.42.1 release notes for the Claude marketplace manifest compatibility fix from #211.
• Keep the Claude marketplace metadata version at 1.0.0 and leave the roadmap unchanged.

Rationale

The merged #211 fix removes duplicate marketplace component declarations while keeping .claude-plugin/plugin.json as the canonical owner of skills and hooks. This release aligns the CLI and both bundled plugin manifests with that compatibility fix.

Validation

• JSON validity checks for marketplace and plugin manifests
• claude plugin validate .claude-plugin/marketplace.json
• claude plugin validate .claude-plugin/plugin.json (only the known non-failing root-CLAUDE warning)
• Focused version/manifest tests
• git diff --check
• PATH-pinned make ci (0 lint issues)
• make test-race
• make release-check from the clean committed branch

This PR contains no tag, draft release, published release, or release assets. Publication remains a separate post-merge, gated operation.
