fix: resolve bookmark lookup for subgraph blueprints (#9057)

## Summary

Bookmarked subgraph blueprint nodes were not appearing in the favorites
tree because `buildBookmarkTree` looked up nodes only in
`nodeDefsByName`, which excludes subgraph blueprints.

## Changes

- **What**: Added `allNodeDefsByName` computed in `nodeDefStore` that
includes both regular nodes and subgraph blueprints. Updated
`nodeBookmarkStore.buildBookmarkTree` to use it for bookmark resolution.

## Review Focus

- `allNodeDefsByName` iterates over `nodeDefs` (which merges
`subgraphBlueprints` + `nodeDefsByName`). Confirm this doesn't introduce
performance concerns for large node sets.
