fix(tmux): pass truecolor through to ghostty#38
Merged
Conversation
The existing terminal-overrides glob *256col*:Tc only matches outer terminals whose TERM contains "256col" (xterm-256color, screen-256color). Ghostty advertises TERM=xterm-ghostty by default, so 24-bit colour stopped at the terminal boundary and tmux fell back to 256. Add an explicit xterm-ghostty:Tc entry. Inert under any other terminal. Prep work for TERM-001-ghostty-bootstrap (separate spec).

Prep work for spec
TERM-001-ghostty-bootstrap(separate, not yet scaffolded). Shipping the tmux fix now as an atomic 1-line change so the moment Ghostty lands locally, truecolor works without re-deploying tmux.conf.Test plan
