Documents the distinction between `widget.serialize` (workflow
persistence, checked by `LGraphNode.serialize()`) and
`widget.options.serialize` (API prompt, checked by `executionUtil.ts`).
These share a property name but live at different levels of the widget
object and are consumed by different code paths — a common source of
confusion when debugging serialization bugs.
Includes:
- Explanation of both properties with code references
- Permutation table of the 4 possible combinations with real examples
- Gotchas section covering the `addWidget` options bag behavior and
`PrimitiveNode` dynamic widgets
- Reference added to `src/lib/litegraph/AGENTS.md`
Context: discovered while debugging #1757 (PrimitiveNode
`control_after_generate` lost on copy-paste).

## Summary
Document why autogrow and matchtype don't work inside subgraphs,
covering root cause, symptoms, workarounds, and historical context.
## Changes
- **What**: Add `src/core/graph/subgraph-dynamic-input-limitations.md`
explaining the static-vs-dynamic impedance mismatch between subgraph
slots (fixed type at creation) and matchtype/autogrow (runtime
mutations). Includes Mermaid diagrams, workarounds, and PR history. Link
added to `src/lib/litegraph/AGENTS.md` for discoverability.
## Review Focus
- Accuracy of the technical explanation — @AustinMroz authored
matchtype/autogrow, @webfiltered authored the subgraph system
- Whether the workarounds section is practical and complete
- File placement: colocated at `src/core/graph/` next to both
`subgraph/` and `widgets/dynamicWidgets.ts`

## Summary
Audits and updates litegraph documentation files that came from the old
litegraph.js repo merged via git subtree (per #8341 discussion).
## Changes
- **Delete** `CONTRIBUTING.md` - completely outdated, referenced
original jagenjo/litegraph.js from 2020
- **Fix** `API.md` - remove Subgraph from "Removed public interfaces"
(actively used in 25+ files)
- **Update** `README.md` - replace standalone releasing instructions
with note about embedded subtree workflow
- **Fix** `AGENTS.md` and `__fixtures__/README.md` - correct import path
typos (`./fixtures/` → `./__fixtures__/`)
Fixes#8347
