Add isolated cargo-fuzz/libFuzzer infrastructure for irtt-proto, fuzzing decode_request, decode_open_reply, decode_echo_reply, Params::decode(_with_presence), and the varint codec against arbitrary and structurally-derived wire input. Each target's core invariant is that arbitrary bytes must never panic; a small clean-room seed corpus (generated from irtt-proto's own encoders) and a bounded nightly smoke CI workflow are included. The fuzz project is its own isolated cargo workspace and does not affect the root workspace, its lockfile, or any published crate's dependency graph.
