9c19452e7dAdd libFuzzer/AFL++ harnesses for the direct-P2P handshake/state/history and delta/bootstrap control parsers. Fuzzers invoke the same production parser seams as the live wire path, so coverage cannot drift from real validation. A protocol-v3 seed exercises exact-version rejection after the v4 upgrade. Bound noninteractive AFL++ campaigns with AFL_FUZZ_SECONDS and register focused fuzz-smoke tests without duplicating broad protocol/delta registrations. Clarify that peer/cycle status is local health telemetry rather than global convergence, and document the remaining decision-grade live-performance gate. Signed-off-by: trvon <git@trevon.dev>
