Subject: [PATCH] Add full keyboard shortcut reference to PLAN.md, fix zoom
 speed

Shortcut table covers all Figma shortcuts organized by category
(tools, file, edit, view, object, text, arrange, canvas interaction)
with implementation status tracking.

Zoom: use continuous exponential scaling (0.99^deltaY) instead of
fixed 1.1/0.9 factor per event.
