CI Health Check - Testing master branch

[ChrisRackauckas-Claude]

Automated CI Health Check

This is an automated CI health check to verify that the continuous integration pipeline is functioning correctly on the master branch.

What this PR does:

• Makes a trivial whitespace change (added blank line to README.md)
• Triggers all CI workflows
• Will be closed once CI status is verified

Next steps:

1. Wait for all CI checks to complete
2. If CI passes: close this PR with success message
3. If CI fails: open an issue with detailed failure analysis and link to failed CI run
