fix: improve widgetStore tests per review feedback

- Remove unsafe `as unknown` casts; use `as const` for V1 tuples, direct objects for V2
- Assert ComfyWidgets.INT identity instead of fragile not.toBe(override)
- Remove change-detector core widgets test that only tests the mock
- Remove redundant registerCustomWidgets test (duplicate of L40-44)
