improve speed and accuracy with read_page, list_interactive helpers

[laithrw]

Summary by cubic

Adds read_page() and list_interactive() to quickly summarize page content and list visible, clickable elements with coordinates, reducing screenshots and speeding up actions. list_interactive() uses the Accessibility tree with a clickable-widget fallback for higher accuracy; prefer verifying outcomes with js(...)/page_info() over extra screenshots.

• New Features

  • read_page(max_chars=4000): converts HTML to clean markdown, strips scripts/styles/JSON, keeps paragraph breaks; falls back to innerText if needed.
  • list_interactive(limit=60, viewport_only=True): AX tree + DOMSnapshot; includes gridcell and roleless clickable widgets; backfills missing names from DOM text; filters by size/viewport and ignores large container delegates; returns x, y, role, and short name.

• Dependencies

  • Added markdownify==1.2.2.
