anti 7389ddb62c chore(web/build): split vendor chunks — 705 kB main bundle → 246 kB ...

Single-bundle build was tripping vite's 500 kB warning per chunk and
forcing every user to re-download the entire app on every deploy.
Manual chunks split the bundle along natural library boundaries so:

- Rarely-changing vendor libs (react-dom, react-router, lucide-react,
  asciinema-player) cache across deploys.
- App code lives in its own `index-*.js` that's the only chunk that
  changes when we ship feature work.

Split shape (manualChunks fn in vite.config.ts):
- charts   — recharts + d3-*
- player   — asciinema-player
- icons    — lucide-react
- router   — react-router / react-router-dom
- react-dom, react
- vendor   — everything else in node_modules

Resulting bundle sizes (gzip):
  index (app):       246 kB  (gz 63)
  react-dom:         182 kB  (gz 57)
  player:            176 kB  (gz 65)
  router:             42 kB  (gz 15)
  vendor:             36 kB  (gz 14)
  icons:              29 kB  (gz 10)

Every chunk under the 600 kB ceiling we now set explicitly. The old
~705 kB single-chunk deploy is gone. No code changes — config only.
