Breaking Changes

CLI Rename

The command-line tool is now vac instead of marp2video:

# Before (v0.3.0)
marp2video slides video --input slides.md --output video.mp4

# After (v0.4.0)
vac slides video --input slides.md --output video.mp4

Update any scripts, aliases, or CI/CD pipelines that reference marp2video.

Go Module Path

The Go module path has changed:

// Before (v0.3.0)
import "github.com/grokify/marp2video/pkg/video"

// After (v0.4.0)
