[FIX] Audit, pre-merge review findings :

- 5 advanced tools had untyped value/defaultValue schema props (animation_add_parameter, shadergraph_set_node_property, scriptableobject_set_field, editorprefs_set, playerprefs_set) -> explicit type unions; new unit test enforces type-shaping across ALL tiers (the protocol test only sees the ~80 exposed tools, which is why these slipped)
- unity_list_advanced_tools validates its string filters (non-string search/category/tool -> clean error, not a raw TypeError from toLowerCase); protocol test added
- batch-wire degrade path pipelines its set-reference calls via Promise.all (order preserved) instead of sequential awaits
- 57 -> 59 tests
- Bump 2.35.2 -> 2.35.3
