refactor: extract shared runCommand utility and cleanup codebase

- Create shared command utility in ts/utils/command.ts
- Update index.ts, process-manager.ts, system-info.ts to use shared utility
- Remove duplicate runCommand implementations from all files
- Remove legacy Chrome wrapper methods (startChrome, stopChrome, isChromeRunning)
- Consolidate Sway window selectors from 5 to 2
- Remove unused isobuild TypeScript files (mod.ts, deno.json, ts/index.ts)
- Make getStatus() async to properly await system info
- Add disk and system info sections to UI
