Patch Changes

• #1754 151d457 Thanks @threepointone! - Add Browser Run Quick Actions to the browser tools: stateless, one-shot
  browsing that needs only the browser binding — no Durable Object, loader, or
  sandbox. New primitives in agents/browser (browserMarkdown,
  browserExtract, browserLinks, browserScrape, browserContent,
  browserSnapshot, browserScreenshot, browserPdf, plus runQuickAction)
  wrap the quickAction() binding and unwrap its { success, result } envelope.
  A new createQuickActionTools({ browser }) (from agents/browser/ai) returns
  AI SDK tools (browser_markdown, browser_extract, browser_links,
  browser_scrape, opt-in browser_content) so an agent can read a page as
  Markdown, extract structured data with AI, or list/scrape elements in a single
  call. Every result is bounded to maxChars (text truncated, oversized
  arrays/objects summarized) to protect the context window, and host-only request
  options (cookies, authenticate, gotoOptions, viewport, …) can be passed
  once via options for authenticated or JavaScript-heavy pages without exposing
  them to the model. createBrowserTools/createBrowserRuntime now expose these tools alongside the
  durable browser_execute tool by default whenever a browser binding is
  present (pass quickActions: false to opt out), and they resolve ctx from the
  current Agent via getCurrentAgent() so ctx no longer has to be passed
  explicitly from inside an Agent. Result bounding is shape-stable — arrays stay
  arrays (trimmed), so the model sees a consistent type, except when even the
  first element overflows the budget, where the result degrades to the
  truncated-preview summary rather than a misleading empty array.
  runQuickAction's params are now typed per action. @cloudflare/think/tools/browser re-exports
  createQuickActionTools and the Quick Action primitives/types so a Think agent
  can expose them from getTools() with a single import. Quick Actions require a
  Worker compatibility_date of 2026-03-24+ and remote: true on the browser
  binding for local wrangler dev.

• #1754 151d457 Thanks @threepointone! - Align the streamed assistant message id with the persisted id during chat streaming. Providers that emit no start.messageId (e.g. Workers AI) previously left the client to generate its own id, so the live stream and the persisted message broadcast couldn't reconcile by id and the originating tab briefly rendered the turn twice before collapsing. The start chunk is now stamped with the allocated assistant id for new turns (continuations are unaffected). Mirrors the same fix in @cloudflare/ai-chat.

• #1754 151d457 Thanks @threepointone! - Bump the default compatibility_date used when generating a Think app's Worker
  config (createThinkWorkerConfig) from 2026-01-28 to 2026-06-11. Apps that
  set compatibility_date in their own wrangler.jsonc are unaffected; this only
  changes the fallback used when none is specified.
