///     Test helper bridging the v2 authoring shape (a typed <see cref="ModbusTagDefinition"/>) to the v3
///     delivery shape (<see cref="RawTagEntry"/>). Under v3 the driver no longer takes pre-declared
///     definitions — the deploy artifact hands it authored raw tags (RawPath + TagConfig blob), and the
///     driver rebuilds the typed definitions via <see cref="ModbusTagDefinitionFactory"/>. These integration
///     profiles + quirk tests keep expressing their intent as typed definitions; this helper serialises each
///     back to its TagConfig blob (via <see cref="ModbusTagDefinitionFactory.ToTagConfig"/>) and packages it
///     as a <see cref="RawTagEntry"/> whose RawPath is the def's <c>Name</c> — so the round-trip through the
///     real mapper reproduces the same definition the test authored, keyed by the same name the
///     read/write/subscribe call sites use. Mirrors the unit-test project's helper of the same name.
