Subject: apply boxdraw patch for perfect box-drawing character alignment

Applied st-boxdraw_v2-0.8.5.diff with manual adjustments for st 0.9:
- Added boxdraw.c to build sources
- Added ATTR_BOXDRAW attribute flag (bit 13, after ATTR_SELECTED)
- Integrated boxdraw detection in tsetchar() function
- Modified xmakeglyphfontspecs() to use boxdraw for applicable characters
- Adjusted indentation for harfbuzz integration compatibility

Benefits:
- Box-drawing characters now align perfectly regardless of font
- Improved visual quality for tmux, tree, dialog output
- Covers Unicode U2500-U259F (lines/blocks) and U28XX (braille)
