caffeine.sh click was working (icon toggled, swayidle restarted) but
the 'Caffeine ON/OFF' notification never appeared. Same root cause as
the prior swayidle bug: waybar's on-click context strips WAYLAND_DISPLAY
from the spawned script's env. notify-send writes to D-Bus (exit 0) but
mako can't display because it has no Wayland socket to render on. Click
appears to do nothing visually.
Fix: extract the /proc/*/environ probe into a shared helper
(restore-wayland-env.sh) and source it from both caffeine.sh AND
start-swayidle.sh. Now any future on-click script in this repo can
`. restore-wayland-env.sh` to inherit the right env.
Verified on tadbit:
- click 1 (caffeine ON): swayidle killed, flag set, 'Caffeine ON'
notification appeared in mako
- click 2 (caffeine OFF): swayidle restarted, flag cleared, 'Caffeine
OFF' notification appeared in mako
Both are visible in makoctl history now.
