Commit Message

tests: add fuzz harness for XMSS stateful signature verification (#2399) (#2400)

* tests: add fuzz harness for XMSS stateful signature verification

Adds fuzz_test_sig_stfl_xmss.c targeting OQS_SIG_STFL_verify for the
two parameter sets specified in #2399:
  - XMSS-SHA2_10_256
  - XMSSMT-SHA2_20/2_256

The fuzzer mutates signature, message, and public_key inputs on each
iteration. Keypairs are generated once via LLVMFuzzerInitialize to
avoid the overhead of XMSS key generation per iteration.

Verified locally: 22.9M iterations in 16s, no crashes detected.
Closes #2399
