v26.7.6 — Box drawing, Thai shaping, readline keys

Mostly a rendering release: box-drawing characters are drawn as native geometry
instead of font glyphs, Thai SARA AM shapes with its base, and the prompt gets
its readline keys back.

Added

• Readline parity at the prompt — Ctrl-P/Ctrl-N, Ctrl-Y, Alt-., and shell fallthrough (#222)
• One Dark Pro built-in theme (by @yetone in #224)
• TERM_PROGRAM / TERM_PROGRAM_VERSION on every local pane (#219)
• Dim inactive panes is now a switch (by @qiudaomao in #214)

Changed

• The build compiles a single resvg stack again (#227, #237, #238)

Fixed

• Box-drawing characters no longer break into dashes between rows (by @yetone in #229)
• Underlines survive box-drawing cells, and stroke weight stays uniform at fractional DPI (#234)
• Thai SARA AM lost its vowel and rendered as a dotted circle (by @mingrath in #230)
• Italic CJK rendered as unrelated CJK on Windows (#233)

New Contributors

• @yetone made their first contribution in #224
• @qiudaomao made their first contribution in #214
