import { CngxOptionFilterHost } from '@cngx/common/interactive'

Description#

Pull-based contract a parent host (e.g. CngxSelectShell with a search input, future filter-driven hosts) implements so individual CngxOption instances can compute their own hidden visibility from a host-owned searchTerm signal and a host-owned matches policy.

Splitting policy from visibility keeps the option agnostic about HOW filtering decides - substring, fuzzy, server-driven - and gives the host a single point of control. Empty search term ALWAYS resolves to "show everything"; the option short-circuits before calling matches.
