## Summary
I modified `vibe-kanban/crates/local-deployment/src/copy.rs` to prevent copy files from overwriting existing files.
**Before:** Files were only skipped if they existed with the same size. Files with different sizes would be overwritten.
**After:** Files are skipped if they exist at all, regardless of size or content. This ensures user files are never overwritten by the copy operation.
