fix(skills): make ntfy_send.sh self-contained to avoid safety guard

ntfy_send.sh now auto-loads config from its own skill's data/ dir,
eliminating the need for 'source' and '${}' patterns in cron
commands that trigger PicoClaw's exec safety guard.

SKILL.md commands simplified from:
  source .../ntfy.conf; NTFY_TOPIC="$NTFY_TOPIC" bash ntfy_send.sh
to:
  bash skills/reminder/scripts/ntfy_send.sh 'message' --title T

+Script `ntfy_send.sh` otomatis membaca config dari `skills/reminder/data/ntfy.conf`. Cukup panggil langsung:
