Jedrzej Kosinski d91c1d8d48 DynamicSlot: typed option dispatch driven by TypeResolver
Replaces the old connected/unconnected fixed-child DynamicSlot with a
type-keyed option list. Each Option declares a 'when' condition (None,
io.AnyType, a single ComfyType, a list, or a MultiType.Input) and the
child inputs revealed when that condition matches the slot's resolved
upstream type.

Selection happens at schema-finalization time using live_input_types
computed by TypeResolver, so API-only workflows (no frontend) get the
same expansion the UI would.

- _io.py: redesign DynamicSlot.Input / Option; auto-derive slotType as
  the union of all non-None when sets; expose it via as_dict so the
  frontend knows what types are accepted; the class io_type stays
  COMFY_DYNAMICSLOT_V3 as the parse-time dispatch tag.
- type_resolver.py: return the auto-derived _slot_io_type for
  DynamicSlot.Input; document the AnyType (*) limitation.
- execution.py: validate links into a DynamicSlot against slotType,
  not the dispatch tag COMFY_DYNAMICSLOT_V3.
- tests: new test_dynamic_slot.py + regression coverage in
  test_type_resolver.py.
