@react-router/dev/vite should populate optimizeDeps.entries from the route manifest

[not-manu]

currently in dev, vite discovers deps lazily as routes are navigated, which triggers re-optimization and a full reload (visible flicker). the plugin already knows every route file, so it could feed them to vite's dep scanner upfront.

workaround in vite.config.ts:

optimizeDeps: {
  entries: ["./app/root.tsx", "./app/routes/**/*.{ts,tsx}"],
},
server: {
  warmup: { clientFiles: ["./app/root.tsx", "./app/routes/**/*.tsx"] },
},

no more mid-session re-optimization flickers after this.

could @react-router/dev/vite just set these by default from the resolved route config? feels like something the plugin is uniquely positioned to do, and a nice ootb dx win.

happy to open a pr if it'd help, lmk if the direction sounds right first :)
