v0.4.0

What's new

• pages find — search pages by title or content for quick ID lookup (wagapi pages find "iris murdoch")
• pages get by path — accept URL paths in addition to numeric IDs (wagapi pages get /blog/my-post/)
• images upload — upload images via CLI (wagapi images upload photo.png --title "My Photo")
• Block type remapping — auto-remap paragraph→text when the target StreamField requires it; warn when no compatible block type exists (fixes silent data loss on non-standard StreamField configurations)
• Empty fields visible — empty StreamField/RichText fields now show (empty) instead of being silently hidden
• Schema footnote — schema detail output notes that required fields are enforced on publish, not draft creation
• Richer images list — dimensions shown alongside title
