chore: backend fixes + vite config + AppShell cleanup

- pyproject.toml: add httpx>=0.27.0 dependency.
- frontend/vite.config.js: bind port to 31400, strictPort, proxy /api -> 31401.
- start.sh: rewrite as detached daemon (nohup + disown + PID files);
  re-running is treated as restart.
- .gitignore: ignore .run/ (PID files).
- frontend AppShell.vue: drop unused GitHub Star link.
