zeekay 4d7b048aa9 pulsar: cross-runtime oracles + sign KAT generator (v0.1.2 follow-on) ...

cmd/sign_oracle/  — emits the canonical Pulsar sign+verify KAT JSON
(Gen + SignRound1 + SignRound2{Preprocess,} + SignFinalize + Verify) for
(t, n) ∈ {2/3, 3/5, 5/7, 7/11}. The C++ port at
luxcpp/crypto/pulsar/cpp/sign/ replays these entries byte-equal.

cmd/cross_runtime_oracle/  — Go writer for the cross-runtime release
gate. Emits a SHA-256 manifest tying together the three canonical
Pulsar KATs (sign, reshare, dkg2). C++ side at
luxcpp/crypto/pulsar/test/cross_runtime_test.cpp replays each KAT and
checks byte-equality (forward direction: 30/30 PASS).

cmd/cross_runtime_verify/  — Go reader for the reverse direction
(C++ writes, Go verifies). Currently 3/3 PASS against the SHA-256s
emitted by luxcpp/crypto/pulsar/cmd/cross_runtime_oracle/.

threshold/testdata/fuzz/FuzzPulsarSign1Round1Data/  — corpus seed for
the in-tree fuzz harness; mitigates the second lattice DoS (issue #4)
where Vector[T].ReadFrom calls make([]T, size) with no bound.

23 fuzz harnesses × 30s = 10.9M execs, 0 panics.
