VHS's frontend extension (web/js/VHS.core.js:2030) gates its
format-widget machinery on `nodeData?.name == "VHS_VideoCombine"` —
strict-equality on the registered node ID. Our subclass uses a
different ID (`Easy_VideoCombine`), so none of VHS's per-format
widget rendering ran. The user saw:
[VideoHelperSuite] - WARNING - Missing input for p has been set to hq
on every execution (profile defaulting to "hq" for ProRes), and
had no way to pick anything other than the default — because the
profile dropdown was never rendered.
Fix: a minimal frontend extension at web/easy_video_combine.js
(~80 LoC) that replicates `addFormatWidgets` for our node name.
Hooks the format dropdown's callback to add/remove per-format
widgets the same way upstream does. Self-contained — does not
import from VHS's module (their helpers aren't exported as ES
imports).
Verifies via the actual ComfyUI install after dev-sync; static
preview servers can't exercise it (depends on LiteGraph's
registered_node_types at runtime).
