* fix(hopper): preserve owned basic-block endpoint instructions * test(hopper): share probe runner and restore fixture hashability Reuse one probe helper with the facade test's execFile options (encoding, timeout, maxBuffer) instead of repeating the invocation. Give the fixture Block a hash consistent with its equality so the equality-based ownership doubles stay hashable. * fix(hopper): align owned instruction walks with normalized block ranges --------- Co-authored-by: Vilmer Frost <frost.vilmer@gmail.com> Co-authored-by: morluto <76467478+morluto@users.noreply.github.com>
