Cathet v4.0.1

Cathet v4.0.1

⚡ Performance & Responsiveness

• Eliminated Keystroke Lag with Embedded Images: Resolved an issue where typing words felt sluggish and delayed after pasting multiple images into the document.
• On-Demand DOM Serialization: Removed continuous full-document re-serialization from the editor's live input keystroke handler. DOM serialization now executes strictly on-demand during file saves and Markdown preview toggles.
• Zero-Reflow Token Substitution: Optimized Base64 pill DOM extraction by substituting lightweight temporary tokens (~25 bytes) rather than inserting full Base64 strings into the active layout tree, eliminating expensive Chromium layout reflow and text-shaping passes over megabytes of image data.

📖 Documentation

• Updated README documentation detailing clipboard optimization workflows and offline guide references.
