## Summary Fix broken link rendering (noodles disappearing or going to wrong positions) when switching between app mode and graph mode tabs. ## Changes - **What**: When the graph canvas is hidden via `display: none` in app mode, slot elements lose valid DOM measurements. On switching back, links rendered at stale coordinates or disappeared. This PR rekeys `LGraphNode` components by workflow path, adds measurability guards to skip hidden slots, clears stale layouts, and watches `linearMode` to trigger a full slot layout resync on mode transitions. ## Review Focus - The `isSlotElementMeasurable` guard skips elements that are disconnected or have zero-size rects — verify this doesn't inadvertently skip slots during normal graph rendering. - The `linearMode` watcher clears all slot layouts when entering app mode and requests a full resync when leaving — confirm no flicker or race with the RAF-based sync scheduler. ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-10273-fix-resync-slot-layouts-when-switching-between-app-mode-and-graph-mode-3276d73d3650812f9366dae53c7b2d37) by [Unito](https://www.unito.io) --------- Co-authored-by: Amp <amp@ampcode.com>
