feat(term): replace vterm with ghostel as the terminal engine

I swapped the terminal engine from vterm to ghostel (libghostty-vt) everywhere. term-config replaces vterm-config (the F12 terminal, the C-; x menu, tmux history capture), and ai-term replaces ai-vterm (the F9 Claude-agent launcher). ghostel renders the agent TUI without vterm's flicker under heavy streaming, and one engine now covers every terminal workflow.

Two behavior changes fall out of the swap. F9 launches in a terminal frame now: ghostel renders in TTY frames, so the old GUI-only guard is gone. Terminal windows no longer dim when unfocused: ghostel resolves its palette into the native module per-terminal, so there's no per-window color hook to dim through the way vterm had.

auto-dim drops its vterm color-advice path, the dashboard Terminal button launches ghostel, and the vterm and vterm-toggle packages are removed. The tmux pane-history and copy-mode machinery carried over unchanged. It keys on the pty tty, which ghostel exposes.

-;;; test-ai-vterm--server-display.el --- Tests for emacsclient window routing -*- lexical-binding: t; -*-
-
-;;; Commentary:
-;; `cj/--ai-vterm-server-display' is wired as `server-window' so a file
-;; opened via `emacsclient -n' (e.g. when Craig tells the agent to open
-;; something) doesn't land on top of the agent vterm.  When the selected
-;; window shows an `agent [...]' buffer, the file goes to a non-agent
-;; window instead -- splitting one off the agent if it is the only window.
-;; `cj/--ai-vterm-non-agent-window' picks that window.
