P0: Electrobun + Angular 22 + Tailwind skeleton boots under Bun

- Electrobun 1.18 shell with branding in src/shared/branding.ts
- Angular 22 zoneless UI in ui/ (workspace), Tailwind v4 shadcn-style tokens
- ng-icons/mynaui icon registry
- Node-version shim so Angular CLI runs under Bun without Node installed
- ssh2 SFTP verified working under Bun against test box
