v0.6.0 — rearrange, paste, and see your links

Editor

• Drag any block to move it: hover a block and grab the handle on its left edge — an insertion line shows where it will land. Works per paragraph, even inside labeled containers. Agents receive moves as a new kind: "moved" edit with landing-spot anchors.
• Paste images from the clipboard: saved into an assets/ folder next to the reviewed file (collision-safe), inserted at the caret, and referenced relatively so the saved file renders standalone. png/jpeg/gif/webp.
• ⌘K links are always visible: on pages whose CSS resets anchor styling, new links now get an underline instead of looking like plain prose.

Fixes

• Windows: inline edits no longer flash a console window or steal keyboard focus (#8, thanks @radesjardins).
• ⌘-clicking #hash links in single-file prototypes now navigates properly (:target, hidden sections), and an overall note can be sent without any edits (#11, thanks @hgambas).
• Overlay repositioning is throttled to once per frame while scrolling.
