ci: prune macOS coverage artifacts

[vivekgsharma]

Summary

• prune stale macOS runner artifacts before Rust tests, including target/llvm-cov-target and old target-backup-before-*-clean-* folders
• lower the emergency target/ cleanup threshold and also clean when free disk drops below 60GB
• remove cargo llvm-cov build artifacts after coverage upload so they do not accumulate between self-hosted runner jobs

Validation

• git diff --check -- .github/workflows/tests-rs-workspace.yml
• python3 -c 'import pathlib, yaml; yaml.safe_load(pathlib.Path(".github/workflows/tests-rs-workspace.yml").read_text()); print("yaml ok")'

📝 Walkthrough

Walkthrough

This PR updates CI runner disk management across two workflow jobs. The macOS test job replaces simple cleanup logic with enhanced disk pruning that removes stale artifacts and conditionally deletes the target directory based on size and available disk thresholds, plus adds end-of-run reporting. The Ubuntu lint job's bash script closure is adjusted for consistency.

Changes

Workflow Enhancements

Layer / File(s)	Summary
macOS disk-pruning and cleanup enhancements .github/workflows/tests-rs-workspace.yml	Replaces the prior "clean target if too large" step with a multi-step disk-pruning approach that prunes stale target-backup-before-*-clean-* and target/llvm-cov-target paths, conditionally deletes target/ when it exceeds a size threshold or available disk drops below a minimum free threshold, and adds an end-of-run cleanup step to remove target/llvm-cov-target and report target size.
Ubuntu lint job bash script adjustment .github/workflows/tests-rs-workspace.yml	Adjusted the final closure portion of the "Detect immutable structure changes" bash block in the Ubuntu lint job.

Poem

🐰 Disk space doth grow, like carrots in spring,
So prune the old artifacts, and freshly clean things,
With thresholds and checks, the runners stay spry,
No disk-full disasters shall make our tests cry! ✨
