chore: checkpoint web Blender migration source, tools and docs

Accumulated uncommitted work: GHOST Web backend, WebGL/GPU web layer,
web workflow engine and protocol, tooling, docs and task records.
Large generated evidence, user-testing archives, build snapshots and
imported test assets remain untracked.

+- Implementation entrypoint: `python3 my-tools/authorize_next_wbv2_task.py --write`
+
+## 目标
+
+授权一个共享 Blender Main/WASM/Chromium 功能批次：AUTO_GEOMETRY_NATIVE_NODE_READER，共 5 个源码/RNA 单元。
+
+## 输入与范围
+
+- Blender source: `blender-5.2.0/source/blender`
+- Fixtures/test: `tests/files/web/generated/wbv2-geometry-95ccfa5892bb7a33.blend`, `web/tests/e2e/geometry-node-main-reader.spec.ts`
+
+## 验收
+
+- prior evidence and dynamic inventory remain hash-bound and immutable
+- one shared function chain validates the complete selected batch
+- missing source, unsupported data, hash drift or false completion remains blocked
+- `node tools/web/check-task-context.mjs --task WBV2-P1237-000 --write`
+
+## 交付与回滚
+
+- Manifest: `tests/golden/WBV2-P1237-000/manifest.json`
+- Status: `docs/status/WBV2-P1237-000.md`
+- Rollback: restore WBV2-P1236-001 as queue parent.
