commit 9ec8bc72c26d942a1a1338893604cc7d5719f1b7
from: Brett Fisher <code@brettfisher.xyz>
date: Mon Jun  8 21:08:00 2026 UTC

bxbar.c, bxbarrc.lua, config.def.h: Use invisible delimiter and
refine spacing.

  - Set DELIMITER to '\x01' (SOH) to prevent visual rendering
    artifacts.
  - Implement gap logic in draw() to enforce consistent 4-space
    separation between left and right elements.
  - Change default bar height.
  - Update bxbarrc.lua to use string.char(1) for delimiter output.
  - Update bxbarrc.lua to find battery path once at startup.
  - Update bxbarrc.lua to get and display battery status.
