(idea) migrate to libghostty

[tiagoefreitas]

libghostty compatible with xterm.js api for better performance and graphics support.

replace xterm.js with libghostty drop-in replacement for :
https://github.com/coder/ghostty-web (original)
https://github.com/rcarmo/ghostty-web (fork with better theme/font rendering)

https://github.com/wiedymi/restty (partial xterm.js api missing buffer/parser/marker, but includes a Pure TypeScript text shaping engine, more rendering options with its own API and Plugin system) - probably best long-term

web terminals for ideas:
https://github.com/tiagoefreitas/webterm (iOS support and tmux dashboard)

Migrating should be just changing the import: @xterm/xterm → ghostty-web

Will test it if I adopt agentboard fully

yea seems worth exploring if performance isn't worse. one thing to check for is accessibility support, that's used for long tap + drag text highlighting on mobile
