fix: resolve syntax error, water pickup, and ground detection bugs

- Remove orphan bot.findBlocks() in auto_sleep that caused a syntax error
  breaking the entire modes.js module (sleep never triggered)
- Equip empty bucket before activateItem() to actually pick up placed water
- Scan 1-6 blocks below for ground instead of checking only at fixed 4-block
  offset, widening the activation window for MLG water
- Use goToBed() return value instead of try/catch (it returns false, not throws)
