Detailed Description

Optional cpp-parcel integration.

Activates when parcel is on the include path (or when TAGVAL_WITH_PARCEL=1 is defined by CMake).

Wire envelope (parcel framing of tagval's bare-string JSON adapter):

DeviceKind::Phone   <->   {"k":"tagval","v":"phone"}

Limitation: every TagValCell<T> instantiation shares kind_id="tagval", so a single ParcelRegistry cannot dispatch by kind to multiple TagT. This matches dimval's documented constraint and is fine for the typical site-knows-the- type usage. Inner JSON validation: T::try_of() (called via the bare-string from_json adapter) reports unknown codes, so cross-kind mismatches still surface as exceptions when the codes don't happen to coincide.
