chore(icons): move icons from public/ to icons/, guard chrome.runtime

- icons/ now lives at repo root (not public/) so CRXJS can copy them
  directly into dist/icons/ without Vite's publicDir interfering
- vite.config.ts: set publicDir: false; remove manual rollupOptions
  input (CRXJS handles all entry points via manifest)
- scripts/gen-icons.mjs: update output path public/icons/ → icons/
- HacklmIcon.tsx: guard chrome.runtime.getURL with typeof check so
  the component works in Storybook / non-extension environments
