* 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
