Research direction

The issue describes that when switching sheets, collaboration should not occur. Investigate the code path that triggers collaboration events when switching sheets. Look at the 'sheetChange' or 'sheetSwitch' handlers in the codebase (likely in src/ or similar). Consider where collaboration (like WebSocket/RealTime collaboration) is invoked and add a condition to skip it during sheet switch. Check if there are any existing flags or state to indicate sheet switching. See issue #214 and related comments.
