Prior to the release of subgraphs, there was a single graph accessed
through `app.graph`. Now that there's multiple graphs, there's a lot of
code that needs to be reviewed and potentially updated depending on if
it cares about nearby nodes, all nodes, or something else requiring
specific attention.
This was done by simply changing the type of `app.graph` to unknown so
the typechecker will complain about every place it's currently used.
References were then updated to `app.rootGraph` if the previous usage
was correct, or actually rewritten.
By not getting rid of `app.graph`, this change already ensures that
there's no loss of functionality for custom nodes, but the prior typing
of `app.graph` can always be restored if future dissuasion of
`app.graph` usage creates issues.

## Summary
Fixes a bug where the queue/execute button was incorrectly disabled with
a warning icon when creating a new empty workflow, due to stale missing
nodes data persisting from a previous workflow.
## Root Cause
When switching from a workflow with missing nodes to an empty workflow,
the `getWorkflowPacks()` function in `useWorkflowPacks.ts` would return
early without clearing the `workflowPacks.value` ref, causing stale
missing node data to persist.
## Changes
- **`useWorkflowPacks.ts`**: Explicitly clear `workflowPacks.value = []`
when switching to empty workflow
- **`useMissingNodes.test.ts`**: Add test case to verify missing nodes
state clears when switching to empty workflow
## Test Plan
- [x] Added unit test covering the empty workflow scenario
- [x] All 20 unit tests pass
- [x] TypeScript type checking passes
- [x] Manual verification: Create workflow with missing nodes → Create
new empty workflow → Button should be enabled
## Before
1. Open workflow with missing nodes → Button disabled ✅ (correct)
2. Create new empty workflow → Button still disabled ❌ (bug)
3. Click valid workflow → Button enabled ✅
## After
1. Open workflow with missing nodes → Button disabled ✅
2. Create new empty workflow → Button enabled ✅ (fixed)
3. Click valid workflow → Button enabled ✅

## Summary
Reorganized custom nodes manager functionality from scattered technical
layers into a cohesive domain-focused module following [domain-driven
design](https://en.wikipedia.org/wiki/Domain-driven_design) principles.
## Changes
- **What**: Migrated all manager code from technical layers
(`src/components/`, `src/stores/`, etc.) to unified domain structure at
`src/workbench/extensions/manager/`
- **Breaking**: Import paths changed for all manager-related modules
(40+ files updated)
## Review Focus
Verify all import path updates are correct and no circular dependencies
introduced. Check that [Vue 3 composition
API](https://vuejs.org/guide/reusability/composables.html) patterns
remain consistent across relocated composables.

- Updated all imports from '@comfyorg/litegraph' to '@/lib/litegraph/src/'
- Replaced deep dist imports with direct source paths
- Updated CSS import in main.ts
- All imports now use the @ alias consistently
