# reinstall.sh — one-shot: install the freshly built .pkg, wipe the shm
# region (so a protocol-version bump doesn't leave both sides refusing to
# attach), restart coreaudiod (forces the HAL driver to re-mmap), and
# bootcycle the two LaunchAgents in the right order (jackd first so the
# daemon doesn't race a not-yet-running server).
#
# Assumes ./installer/build-pkg.sh has already produced
# ./installer/build/JackBridge-<version>.pkg. Picks the newest .pkg in that
# directory if multiple exist.
