Fix typo and inconsistent heading levels in README

- Fix typo: "cross-platfom" → "cross-platform" in TestDriver description
- Fix heading levels: Change Web-Based Tools subsections from #### to ###
  to match the table of contents hierarchy (App Builders, UI Generators,
  Coding Agents, Codebase Intelligence, Database & SQL, Snippet & Utility
  Tools, ChatGPT Plugins)
