Upgrades playwright-core, playwright, and @playwright/test to 1.64.1 and wraps the new 1.64 APIs.

Breaking changes

• Page.content and Frame.content are now methods taking Playwright's new includeShadow option. Replace yield* page.content with yield* page.content().
• The @playwright/test peer dependency now requires ^1.64.1.
• Playwright 1.64 considers elements inside hidden iframes hidden for actions and Locator.isVisible().

New APIs

• Locator.within(locator): accepts a wrapped or a native locator, like and/or.
• Page.getByRef(ref): locates an element by an aria ref from ariaSnapshot({ mode: "ai" }).
• Page.webmcp and Frame.webmcp: backed by the new Playwright.WebMCP service (tools(), callTool()) with named WebMCPTool / WebMCPToolAnnotations types.
• includeShadow option on Page.content() / Frame.content().
• The new fps and action style video options flow through the existing Playwright option types.

Fixes

• Tracing.start and Tracing.startChunk now return a Disposable in Playwright 1.64. The wrapper drops it so the result stays void, as Screencast.start already does.

Not wrapped

• APIRequestContext cookie methods (addCookies, cookies, clearCookies): this library does not wrap APIRequestContext yet.

Verification

• pnpm check, pnpm type-check, pnpm test (109 tests), and pnpm check-doc-examples pass.
• Smoke-tested against Chromium 156: within resolved per-row cells, content({ includeShadow: true }) serialized the shadow root, getByRef resolved a ref from an ai aria snapshot, and webmcp.tools() / callTool("add", { a: 2, b: 40 }) returned the registered tool and "42" (with --enable-features=WebMCP, page served over HTTP).
