InjectionToken<CngxFormFieldHostContract>
Description#
Injection token resolving to the surrounding form-field-host contract,
if any. Provided by CngxFormFieldPresenter (in @cngx/forms/field)
via useExisting so any control mounted inside a cngx-form-field
can read showError and call markAsTouched() reactively without
referencing the concrete presenter class.
Optional in standalone use: a control mounted outside a
cngx-form-field should inject with { optional: true } and treat
the absence as "no field-level visibility gate, no touched-feedback
channel".
