v0.7.2

v0.7.2: Error handling improvements

🐛 Bug fixes

• Fix mdcmd to exit with non-zero code when embedded commands fail - Previously, mdcmd would exit with code 0 even when commands failed, breaking shell scripts using set -e
• Commands that fail no longer crash with stack traces
• Failed commands are now reported gracefully with exit code and output
• Other commands continue to execute in concurrent mode when one fails

📦 Dependencies

• Bump utz requirement to >=0.21.1 (includes fix for text() handling None return values)

🧪 Tests

• Add tests for command failure handling
• Add tests for mixed success/failure scenarios
• Add tests to ensure no uncaught exceptions on errors

📝 Documentation & Infrastructure

• Improve README copy and formatting
• Add dynamic README/PyPI link generation with new scripts:
  • scripts/gh-url.py - Generate GitHub URLs for links
  • scripts/gh_url_utils.py - Shared utilities for URL generation
  • scripts/raw-readme-link.py - Generate raw README section links
• Remove test/print-ci-yml-ref.py (replaced by new link generation approach)
• Use footer-style link definitions for better maintainability

⚙️ CI Improvements

• Update to astral-sh/setup-uv@v7
• Run CI on pull requests
