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.
