GodopuandClaude Opus 5.5 515b3206b9 chore(shellcheck): no new findings in the update skill, lib.sh and install.sh (Issue #72)
CI now shellchecks the update skill's scripts: SC1091 is disabled at their
`source` lines as in the other skills, and the two findings this branch added
(lib.sh's loop_lock.sh source, install.sh's one-item legacy loop) are
disabled at their lines.

# Run by install_phase.sh from the NEWLY installed tree, in its own process:
# converts the registry with the new code's entry point (lib_py.registry_format,
# #71) and starts the monitor again if it ran before the update. Exit 0, or
# nonzero when the conversion or the monitor restart failed (the install is
# kept either way: the registry converts again on its next write).
