serializeResultForTesting used QJsonValue::fromVariant, which cannot
convert the custom LogosResult metatype and silently degraded a
`result`-type return to the literal "null". A QML-only ui_qml plugin
calling a result-returning method through logos.callModule therefore
received null instead of {success, value, error}.
Replace the bespoke serialization with logos-protocol's canonical
logos::qvariantToNlohmann — the same converter every transport
(lp/std/cdylib) already uses. Now ALL types round-trip to QML/JS
identically: scalars as bare literals, containers preserved, integers
kept as integers (QJsonValue::fromVariant degraded them to double),
bytes in the tagged {"_bytes":...} form, and LogosResult as
{success, value, error} (empty error -> null). Fixes both sync
callModule and async callModuleAsync.
Adds test_logos_qml_bridge_result.cpp (regression) plus the
reproduction/isolation harnesses (e2e, gui, handshake, 2-process) built
while proving the long-suspected QML "sequential-call stall" is NOT an
SDK defect: every layer round-trips correctly under isolation, and the
only real bug was this result serialization.

// Regression guard for the QML-only `result`-type bug: a `result`-returning
|
|
// method (e.g. makeResult) comes back as a custom LogosResult QVariant, which
|
|
// QJsonValue::fromVariant cannot convert — serializeResultForTesting used to
|
|
// degrade it to the literal "null", so QML's JSON.parse produced null and every
|
|
// result round-trip failed. It must instead emit the canonical
|
|
// {success, value, error} shape (empty error -> null), identical to the lp/std
|
|
// transport, so `logos.callModule(...)` of a result method round-trips to QML.
