/**
 * The bounded Variant subset Godot's remote debugger speaks on the wire.
 *
 * Debugger packets are `[uint32 length][Variant]`, and every Variant the
 * profiler stream carries is a nil/bool/int/float/string/array or a packed
 * numeric array. Objects, dictionaries and vectors are deliberately *not*
 * decoded: an unrelated debugger packet must fail loudly instead of driving
 * allocation from an attacker-shaped length field. Callers treat a decode
 * failure as "not a message I care about" and move on.
 *
 * Separate from `bridge-protocol.ts` — that framing is ours and both ends are
 * in this repo; this one is Godot's and only the engine defines it.
