A concurrent gmake clean (update_head_reference.sh, precommit_check.sh)
unlinks ./_typhoon out from under a fuzz loop mid-run, breaking every
subsequent iteration with "not found/executable". Observed live running
this alongside update_head_reference.sh today. Copy once up front instead
of exec'ing $BIN in place, so later rebuilds in the working tree can't
touch what the loop is actually running.

Add fuzz_test.sh: a long-running gdb-driven fuzz loop over cross_sectional_200k.ep_2026-09-19T01:17:39ZScott Gaschscott@gasch.org2026-09-19T01:17:39Zurn:sha1:284113f878444ded9cd36b4a70900efd036651de
Documents two build/invocation bugs hit getting this working: DEBUG builds
need MP=1 too or --cpus is silently unrecognized, and gdb's
"handle SIGTRAP nostop noprint pass" breaks thread control against the
MP/pthread binary (misdiagnosed at first as a sandboxed ptrace restriction,
but reproduces outside any harness and goes away once that directive is
dropped).
