feat: include GitHub workflows in npx spec-flow init and update

- Added installWorkflows() function to copy .github/workflows/ directory
- Workflows now install during both init and update commands
- Uses same conflict resolution strategy as other files (merge by default)
- Respects --strategy flag (merge|backup|skip|force)
- Skips existing workflow files during update to preserve customizations

Fixes issue where workflows were only installed via postinstall, not via CLI commands
