Summary

Added WebMCP API access, custom video frame rates, CSS‑styled action decorations, VP9 encoding and deprecated the fontSize option.
Extended the test runner with testProject.default, shuffle and lock options, WebP screenshots, locator.within, page.getByRef, includeShadow, signCount, filteredProjects, and cookie management on apiRequestContext.
Breaking changes: device descriptors now forward the screen property, JSX compilation follows tsconfig settings, updateSnapshots=missing now passes, and elements in hidden iframes are treated as hidden.
