feat: add Gmail skill with rich HTML formatting guidance (#246)

Create a skills architecture for the extension, starting with a Gmail
skill that provides:
- Rich text HTML email formatting instructions (issue #58)
- Gmail search syntax reference
- Label management workflows (system vs custom labels)
- Attachment download guidance
- Threading and reply best practices

Also:
- Migrate Gmail-specific content from WORKSPACE-Context.md to the skill
- Update release.js to bundle the skills/ directory in release archives

Closes #58

- 'test' job now depends on 'verify' and only runs tests across the OS/Node matrix.
- Reduces redundant checks and speeds up the feedback loop.
