Faster editing in large workspaces

ImprovedFaster typing and panel opening in large workspaces. Typing in long documents is smoother, side panels like related content open faster, and expanding or collapsing a section no longer causes a visible stutter. The gains are largest in big workspaces with long outlines and busy panels.
FixedFixed expand/collapse quirks in side panels. Some sections showed an "Expand" label but did not respond to clicking. Expanding or collapsing any section also keeps your keyboard focus in place instead of moving it.
FixedMarking nodes done no longer touches other fields. Marking a tagged node done or not done through the API or MCP, or when importing Tana Paste content, could overwrite other field values on that node. Now only the done status changes.
FixedDrags and selections finish cleanly when you switch away. Resizing a column, dragging a panel, or selecting multiple nodes could get stuck if you switched to another window mid-drag. These now finish properly instead of leaving a stale drag active.
FixedEdits no longer silently stop saving after an error. A rare error during editing could quietly disable saving until you reloaded the page, so further changes never persisted. Saving can no longer get stuck off this way.
FixedFewer unnecessary delete confirmations. Deleting a node no longer prompts for confirmation when its only counted references come from search results or its own descendants, since those are removed along with it anyway.
