🤖 refactor: update VS Code extension branding from 'cmux' to 'mux'

- Update extension name, display name, and description in package.json
- Update command IDs from cmux.* to mux.*
- Update all user-facing strings in error messages and UI
- Fix domain reference to use correct live domain (cmux.io)
- Update GitHub workflows to use mux-*.vsix artifact naming
- Add VS Code marketplace publishing to release workflow

The extension now correctly uses 'mux' as the product name while
pointing to the correct documentation domain.

Generated with `mux`
