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.

register_dynamic_input_func is a private helper (underscore module, not
in __all__, not re-exported). Its only callers are the three core
setup_dynamic_input_funcs() registrations, all of which were updated
together. No third party can be relying on the old 5-arg signature, so
the inspect.signature shim and accompanying backward-compat tests are
over-engineered.

* Add _parse_link helper validating both node_id (str) and slot_idx (int,
rejecting bool) so malformed API JSON (e.g. ['n1', '0']) degrades to
AnyType instead of crashing with TypeError.
* Add slot_idx type guards in resolve_output_type and is_output_list.
* Extract _get_class_def_for_node helper to dedupe node/class lookup
across resolve_output_type, is_output_list, get_declared_slot_io_type.
* register_dynamic_input_func now detects 5-argument legacy callables
via inspect.signature and silently wraps them; preserves backward
compatibility for any custom node that registered its own dynamic
input expansion against the pre-live_input_types signature.
* Tests: malformed link (str slot idx, wrong arity), bad slot type
directly to resolve_output_type, non-string class_type. Tests for
the legacy 5-arg shim and the modern 6-arg passthrough, including
callables with uninspectable signatures.
