cmux ships patched xterm-ghostty and xterm-256color terminfo entries so
the embedded renderer keeps the same color behavior even when the reported
TERM changes.
These overlays patch the terminfo capabilities so that tput setaf 8 (and
similar "bright" colors) uses 256-color indexed sequences (38;5;<n>m /
48;5;<n>m) rather than SGR 90-97/100-107. This avoids relying on bright SGR
handling and fixes zsh-autosuggestions (default fg=8) visibility issues in
cmux while preserving Ghostty's truecolor capabilities.
The build phase Copy Ghostty Resources overlays this directory onto the app
bundle's Contents/Resources/terminfo after copying Ghostty's resources.
