Remove multiple sources of truth and async sync chains that caused
values to be lost during load/switch workflow or reload page.
Changes:
- Remove internalValue state variable from main.ts
- Update getValue/setValue to read/write DOM directly via widget.inputEl
- Remove textValue reactive ref and v-model from Vue component
- Remove serializeValue, onSetValue, and watch callbacks
- Register textarea reference on mount, clean up on unmount
- Simplify AutocompleteTextWidgetInterface
Follows ComfyUI built-in addMultilineWidget pattern:
- Single source of truth (DOM element value only)
- Direct sync (no intermediate variables or async chains)
Also adds documentation:
- docs/dom-widgets/value-persistence-best-practices.md
- docs/dom-widgets/README.md
- Update docs/dom_widget_dev_guide.md with reference
- Fix infinite reinitialization loop by only validating stale widget.inputEl when it's actually in DOM
- Improve findWidgetInputElement to specifically search for textarea for text widgets, avoiding mismatches with checkbox inputs on nodes like WanVideo Lora Select that have toggle switches
- Add data-node-id based element search as primary strategy for better reliability across rendering modes
- Fix autocomplete initialization to properly handle element DOM state transitions
Fixes autocomplete failing after Canvas ↔ Vue DOM mode switches and WanVideo node always failing to trigger autocomplete.

Add data-capture-wheel attribute to SingleSlider and DualRangeSlider
components to prevent wheel events from being intercepted by the canvas
in ComfyUI's new Vue DOM render mode. This allows mouse wheel to work
for adjusting slider values while still enabling workflow zoom on
non-interactive widget areas.
Also update event handling to use pointer events with proper stop
propagation and pointer capture for reliable drag operations in both
rendering modes.
Update development guide with Section 8 documenting Vue DOM render mode
event handling patterns and best practices.
Add `forwardMiddleMouseToCanvas` utility to forward middle mouse button events from DOM widgets to the ComfyUI canvas, enabling workflow panning when the cursor is over a widget. The function is implemented in `vue-widgets/src/main.ts` and documented in the developer guide. Additionally, fix `getPoolConfigFromConnectedNode` to return null for inactive pool nodes.
- Document dual UI systems: standalone web UI and ComfyUI custom node widgets
- Add ComfyUI widget development guidelines including styling and constraints
- Update terminology in LoraRandomizerNode from 'frontend/backend' to 'fixed/always' for clarity
- Include UI constraints for ComfyUI widgets: minimize vertical space, avoid dynamic height changes, keep UI simple
- Add performance note explaining that providing `getMinHeight` and `getHeight` via `options` avoids expensive DOM measurements
- Expand dynamic resizing section with detailed update sequence and common scenarios table
- Update LoraPoolSummaryView.vue with `min-height: 0` to allow flex shrinking
- Update main.ts to provide `getMinHeight` via options and adjust `computeLayoutSize` for performance
- Update documentation to reflect new widget filename `lora-manager-widgets.js`
- Remove `LoraManagerDemoNode` import and registration from `__init__.py`
- Translate development guide from Chinese to English for broader accessibility
- Clean up obsolete demo references to align with actual widget implementation
