CI Health Check - Automated Test

[ChrisRackauckas-Claude]

Automated CI Health Check

This is an automated CI health check to verify that the master branch's CI pipeline is working correctly.

Purpose: Proactive monitoring to detect CI breakage early

Changes: Trivial whitespace addition (blank line added to README.md)

Next Steps:

• CI will run on this PR
• After ~2 hours, results will be analyzed
• 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

Expected Duration: CI typically takes 1-2 hours to complete

---

This is an automated health check. The trivial change will not be merged.
