New React Features

• <ViewTransition />: Adds <ViewTransition /> and addTransitionType APIs to power View Transition animations in React (@​sebmarkbage, @​jackpope, @​gaearon: #31975, #31987, #31996, #31999, #32001, #32002, #32028, #32029, #32031, #32034, #32038, #32041, #32050, #32090, #32105, #32254, #32379, #32422, #32462, #32540, #32545, #32585, #32599, #32611, #32612, #32617, #32651, #32653, #32656, #32664, #32699, #32723, #32734, #32751, #32752, #32760, #32761, #32764, #32772, #32790, #32819, #32820, #32822, #32833, #32849, #33094, #33191, #33200, #33206, #33293, #33330, #33331, #33332, #33357, #33362, #33433, #33576, #34374, #34450, #34481, #34500, #34502, #34510, #34511, #34539, #35567, #35564, #35485, #35380, #35063, #35060, #34676, #36917, #35337, #35520)
• Fragment Refs: Add Refs to <Fragment /> to support composable platform behavior (@​jackpope, @​sebmarkbage, @​eps1lon, @​Dhakshin2007, @​chirokas, @​teamleaderleo, @​fallintoplace: #32465, #32613, #32619, #32654, #32660, #32682, #32722, #32813, #32814, #33056, #33058, #33093, #34069, #34103, #34544, #34545, #37062, #37061, #37060, #36047, #36010, #35642, #35641, #35637, #35630, #34935, #37457, #37408, #37326, #37251, #37171, #37169, #37168, #37167, #37166, #37165, #37164, #37163, #37162, #37161, #37160, #37125, #37063)

New React DOM Features

• browser(): a new react-dom API that returns a usable which errors during server rendering and resolves in the browser. use(browser()) inside a <Suspense> boundary marks a subtree as browser-only without reporting a recoverable error (@​gnoff: #37143, #37241)
  • Added an onBrowserBailout option to the react-dom/server APIs to observe when a subtree defers to the browser (@​gnoff #37193)

Notable changes

• Enable Trusted Types API integration (@​rickhanlonii #35816)
• Transitions now render independently instead of being entangled into a single render, so a slow transition no longer holds up unrelated ones (@​acdlite #37290)
• Added a DEV-only warning when a component appears to have been unblocked by calling use() conditionally (@​hoxyq, @​eps1lon: #37104, #37203, #37491)

Fix with agent prompt

### Issue 1
src/agent_env/explorer/ui/package.json:28
React moves to 19, but the lockfile keeps dependencies that exclude it: `react-dom@18.3.1` requires React 18, and `lucide-react@0.252.0` only accepts React 16–18. Likewise, `@types/react-dom@18.3.7` requires React 18 types, while `@types/react` moves to 19.

CI runs plain `npm ci`, so these conflicts block installation before the checks and static build start. Update the renderer, its types, and the incompatible icon dependency together, then regenerate the lockfile.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.

Summary

Updates the explorer UI to react@19.3.0 and @types/react@19.3.0.

• The Explorer UI requests React 19 with matching React types.
