Update README for the main branch and document the serve command

[Copilot]

README still referenced master in a few GitHub-hosted asset and installer URLs, which breaks or misroutes documentation for the current default branch. This updates those links to main so branch-specific docs assets resolve correctly, and adds missing documentation for the standalone serve command.

• Branch-specific GitHub URLs

  • Switched the Codecov badge URL from branch/master to branch/main
  • Updated the landing image URL to load from main
  • Updated the install command to fetch install.sh from main

• Serve command documentation

  • Added a feature callout for the dedicated lab serve command
  • Added a short standalone usage example showing how to serve one or more directories without running tests

• Documentation impact

  • Keeps copy-paste install instructions aligned with the current default branch
  • Prevents branch drift in externally hosted README assets
  • Makes the new static file serving workflow discoverable in the README

@copilot you forgot to mention there is a new "serve" command.

Added README coverage for the new lab serve command in commit e861482, including a short standalone usage example alongside the existing CDN docs.
