tty7: a GPU-rendered, daemon-backed terminal in pure Rust

tty7 is split into two Rust processes: a persistent daemon that owns the
shells and a GPU-rendered client that talks to it over a local socket.
Because the shells live in the daemon, quitting and reopening the app
leaves the session intact — detach and reattach, no tmux required.

- Persistent sessions — the daemon holds the PTYs and child processes, so
  closing a window or swapping in a new build never takes a shell down.
- Performance — an 11 MB `cat` completes in 95 ms and DOOM-fire renders at
  888 fps; the daemon drains the PTY at device speed off the render path.
- Shell-aware — new tabs and splits open in the current working directory;
  zsh, bash, fish, and PowerShell are set up automatically.
- Enhanced prompt — inline completion, syntax highlighting, history, and
  in-terminal search, with rich flag/subcommand signatures for common tools.
- Tabs, resizable splits, a command palette, click-to-open links, desktop
  notifications, eight themes, and CJK/IME input.

Native builds for macOS, Windows, and Linux.
Built on Zed's gpui and Alacritty's VT core.
