feat(term): toggle EAT instead of ghostel on F12

F12 now creates and toggles a single EAT terminal (pure-elisp, fully themeable) instead of a ghostel one, reusing the existing dock-and-remember geometry toggle. ghostel stays for ai-term on M-SPC. The EAT terminal runs a plain shell with no tmux. F12 and C-; are bound in EAT's semi-char and mode keymaps so they reach Emacs from inside the terminal (EAT forwards unbound keys to the shell otherwise). Retargeted the toggle's buffer predicate and create-new path from ghostel to EAT, and updated the buffer-filter tests to the EAT semantics.
