fix: integrate just build system with GitHub Actions release workflow

- Install just command runner in CI environment
- Use custom packaging process (just package) instead of direct vsce package
- Disable built-in vsce packaging in semantic-release-vsce to avoid dependency conflicts
- Leverage the project's custom scripts/package.js for clean VSIX creation
