Optional helpers for a shared host: trim-target deletes stale test executables from the
persistent cargo target dirs, gate-lock is a FIFO flock for heavy and timing-sensitive gates,
lite-env sources debug-info-off cargo settings. Copies of the host-side scripts with these
differences:
- trim-target: the default scratch dir is `${XDG_CACHE_HOME:-$HOME/.cache}/komorebi-fast-check`
(was a /tmp/claude-1000/... scratchpad path), the same as fast-check;
- gate-lock: GATE_LOCK_DIR defaults to `${XDG_STATE_HOME:-$HOME/.local/state}/komorebi-gate`
(was /home/jado/komomono-work/.gate), in the header and in the code;
- gate-lock: "/proc/$pid/cmdline" is quoted and a shellcheck directive disables SC2012 and
SC2016 (ls of plain queue ticket names, and a bash -c script expanding its own $1);
- lite-env: a `# shellcheck shell=bash` first line.
Not committed: mini (host and credential specific), host-sample and jitter-probe (host
measurement), the .bak files.
Verified: bash -n and shellcheck clean. Not run: gate-lock was tested by its author with a scratch
GATE_LOCK_DIR before this change; the default path change is untested.
