Manual backport of #11779 to `core/1.43` for inclusion in `v1.43.16`.
Cherry-picked from upstream merge commit `b8dfbfc0b`.
## Why
When inside a subgraph, the parent key handler intercepts the escape key
before `processKey` is called, causing a stale ghost node to be added to
the inner subgraph when the graph is changed to the parent. Moves escape
handler to document, prevents propagation, and adds a safety-net cancel
in `setGraph`.
## Conflict resolution
- `browser_tests/tests/nodeGhostPlacement.spec.ts`: PR adds 6 new test
cases inside the existing `describe` block. Conflict was
non-overlapping/additive — accepted all PR additions (existing tests
untouched). All referenced helpers (`comfyPage.subgraph`,
`Comfy.Graph.ConvertToSubgraph`, `Comfy.PublishSubgraph`,
`comfyPage.visibleToasts`) verified present on `core/1.43`.
- Test file rename `LGraphCanvas.ghostAutoPan.test.ts` →
`LGraphCanvas.ghost.test.ts` (intentional consolidation in PR) carried
through cleanly.
## Validation
- `pnpm typecheck` ✅
- `pnpm test:unit -- run
src/lib/litegraph/src/LGraphCanvas.ghost.test.ts` ✅ (11/11 passing)
- `pnpm exec eslint <changed files>` ✅ (0 errors)
- `pnpm exec oxfmt --check` ✅ (clean)
Source identical to upstream `b8dfbfc0b`, baking on `main` through
`v1.44.x`.
