Terry Jia f1d5337181 Feat/glsl live preview (#10349)
## Summary
replacement for https://github.com/Comfy-Org/ComfyUI_frontend/pull/9201

the first commit squashed
https://github.com/Comfy-Org/ComfyUI_frontend/pull/9201 and fixed
conflict.

the second commit change needed by:
- Enable GLSL live preview on SubgraphNodes by detecting the inner
GLSLShader and rendering its preview directly on the parent SubgraphNode
- Previously, SubgraphNodes containing a GLSLShader showed no live
preview at all To achieve this:
- Read shader source, uniform values, and renderer config from the inner
GLSLShader's widgets
- Trace IMAGE inputs through the subgraph boundary so the inner shader
can use images connected to the SubgraphNode's outer inputs
- Set preview output using the inner node's locator ID so the promoted
preview system picks it up on the SubgraphNode
- Extract setNodePreviewsByLocatorId from nodeOutputStore to support
setting previews by locator ID directly
- Fix graphId to use rootGraph.id for widget store lookups (was using
graph.id, which broke lookups for nodes inside subgraphs)
- Read uniform values from connected upstream nodes, not just local
widgets
- Fix blob URL lifecycle: use the store's
createSharedObjectUrl/releaseSharedObjectUrl reference-counting system
instead of manual revoke, preventing leaks on composable re-creation
