Release v0.3.1: per-side edge collapse buttons

Place collapse buttons on the side where edges actually exit (top/right/
bottom/left) instead of a single button fixed on the right. Each button
independently collapses/expands only the edges on its side, with badge
counts reflecting the per-side subtree. Buttons offset further outward
to avoid overlapping anchor points.

v0.3.0

Release v0.3.0: edge-drop creates note, subtree collapse, UX fixes

- Anchor drag to empty space → auto-creates a connected note at drop position
- Per-note collapse button collapses/expands ALL outgoing edges and their subtrees at once; collapsed count shown as badge
- viewOnly mode: collapse/expand works visually but reverts on exit (snapshot/restore pattern, same as note dragging)
- readOnly/viewOnly: disable pointer events on edge hit areas (no hover cursor/glow)
- Standalone HTML: persist lock and viewOnly states in localStorage across page reloads
- Remove per-note chevron collapse from v0.2.0 (replaced by edge-based subtree collapse)
- README: add dedicated mode documentation (readOnly vs viewOnly comparison table)
- Bump version to 0.3.0, update README and CHANGELOG
