Walkthrough

The changes introduce a version initialization system that extracts build version information from Go build metadata. A new defaultVersion constant is added, an initVersion() function reads build information at startup to set the application version when available, and corresponding tests validate the initialization behavior.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

• The version initialization logic in version_info.go requires careful review to ensure build info reading is safe and conditional logic correctly prioritizes preset versions
• The test file uses mocking patterns that should be verified for correctness and proper cleanup
• Interaction between initVersion() call timing in main() and the global version variable state needs verification

Poem

🐰 A constant is born, so steadfast and true,
Build info now flows through the version anew,
Tests guard the logic with mocks held tight,
The dev version dances in morning light!
