 * Internal base class for `mdc-chip-set` — the container that owns roving
 * tabindex and optional single-select coordination across its `mdc-chip`
 * children.
 *
 * Chips are self-managing views: each chip owns its own `selected` state and
 * reports activation through the `chip-toggle` event. The set enforces the
 * single-select mutex, re-emits committed changes as a composed
 * `chip-set-selection` event, and roves focus with Arrow keys / Home / End
 * (mirroring the Material Web chip-set semantics).
