[ChrisRackauckas-Claude]

Automated CI Health Check

This is an automated CI health check to proactively monitor the health of the continuous integration system.

Purpose

• Verify that CI workflows are functioning correctly
• Detect any breakage in the master/main branch
• Ensure all automated checks pass as expected

What's in this PR

• Trivial whitespace change to trigger CI (blank line added to README.md)
• No functional changes to the codebase

Next Steps

• Will monitor CI results for approximately 2 hours
• If CI passes: PR will be closed and branch deleted
• If CI fails: An issue will be opened with diagnostic information and @ChrisRackauckas will be notified

This is part of proactive repository maintenance to catch CI issues early.
