Summary

__bounds_safety_soft_trap() counts violations via counter(9), fires a
SDT probe carrying the trap site, and continues instead of panicking.
Console logging is opt-in and rate-limited. The deliberate-violation
test hook lives in a separate file so enabling it never instruments the
handler itself.
