commit 485331c7b91c5ef04485d8fb089ae6d2f07fa137
from: Brett Fisher <code@brettfisher.xyz>
date: Fri May 15 21:26:23 2026 UTC

bxbar.c, config.def.h: Set left/right split rendering via DELIMITER.

  - Extract text truncation into text_fit() helper.
  - Split stdin on DELIMITER so text before the delimiter renders
    left-aligned and text after renders right-aligned.
  - Falls back to full left-aligned rendering when no delimiter is present.
