New libFuzzer/AFL++ harnesses, each trapping on an oracle violation:
p2p_json (nesting bound, round trip), p2p_connstr (endpoint round trip,
pin idempotence, no silent re-pin), p2p_handshake (validators and the
full acceptor bind the TLS peer), p2p_delta_stream (batch, session and
bootstrap receive paths stay inside count and byte budgets), p2p_inbound
(the manager inbound session through registry update) and
topology_codec (decoded snapshots re-encode losslessly). p2p_delta now
draws its exchange limits from the input.
p2p_seeds.py writes framed-session seeds for FuzzedDataProvider layouts,
dicts/p2p.dict carries the frame vocabulary, generate_corpus.sh accepts a
local seedgen, and fuzz.sh no longer fails on macOS bash 3.2 when a
target has no dictionary. The generated corpus stays untracked.
