feat(catalog): publish every dynamic-combo option in the widget catalog

[skishore23]

Summary

The widget catalog (comfy nodes widget-catalog, which pins the doc host's applier) expands each COMFY_DYNAMICCOMBO_V3 at its first key only (Graph.widget_order_default). The applier therefore cannot name, validate or position the sub-widgets of any other selection.

Measured on stg-v2 and nightly agent traces (2026-09-20 to 21): after set_widget 1.mode faithful on MagnificImageSkinEnhancerNode, the doc host refused 1.mode.skin_detail with "available: sharpen, smart_grain, mode", although list_slots had just advertised it (~10 unknown_widget failures, also on Minimax and Tripo nodes). comfy-multi-player records this as the BE-9176 workaround (_extra_N placeholder names) "pending a value-aware catalog from comfy-cli".

Each catalog entry with a dynamic combo now carries:

"dynamic_combos": {
  "mode": {
    "default": "creative",
    "options": {
      "creative": {"widgets": [], "defaults": {}},
      "faithful": {"widgets": ["mode.skin_detail"], "defaults": {"mode.skin_detail": 80}}
    }
  }
}

This mirrors the frontend (src/core/graph/widgets/dynamicWidgets.ts): an option's inputs are named <selector>.<key> (required, then optional), the widget-backed ones are inserted right after the selector, and they are seeded from spec defaults when the selection changes. A nested selector gets its own entry. widget_order is unchanged, so existing consumers keep working. The contract test asserts that expanding the catalog for every selection reproduces Graph.widget_order_for_node.

Companion: Comfy-Org/comfy-multi-player#240 consumes dynamic_combos.

📝 Walkthrough

Walkthrough

The change adds tests for dynamic-combo catalog contents, nested selector expansion, default values, and parity with engine widget ordering.

Changes

Dynamic Combo Catalog

Layer / File(s)	Summary
Catalog contract and fixture tests/comfy_cli/test_widget_catalog_dynamic_combos.py	Documents the catalog contract and adds object information containing a nested dynamic-combo node.
Catalog shape assertions tests/comfy_cli/test_widget_catalog_dynamic_combos.py	Checks that each option exposes its direct widgets and defaults. It also checks that classes without dynamic combos omit dynamic_combos.
Catalog expansion and engine parity tests/comfy_cli/test_widget_catalog_dynamic_combos.py	Adds helpers that expand selected options and resolve nested selector positions. Parameterized tests compare every selection with Graph.widget_order_for_node.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to 5b2f0

The new dynamic-combo catalog tests cannot pass until the catalog publishes the required metadata. Implement that metadata before merging.

catalog metadata before merging the test expectations, ensuring entries such as
MagnificImageSkinEnhancerNode expose the dynamic_combos key. Preserve the
