v0.30.0

Added

• A built-in Playwright-backed web platform reuses AUA's semantic analyze, stable selectors,
  actions, screenshots, waits, flows, maps and sessions for HTTP(S) pages. DOM test ids and HTML
  ids become resource_id; only viewport-intersecting nodes satisfy presence checks.
• aua browser and matching MCP tools add browser diagnostics, cookies/web storage and cache
  controls, offline/throttling, scoped CORS, context proxy, HAR record/replay, request mocks,
  session reset, popup/tab/frame inspection, and Playwright traces. URL path/query is now the
  shared map surface, and goal cleanup restores the browser session baseline.
