fix(eat): exclude eat-mode from global font-lock

EAT paints its whole palette with manual face text properties. Inside global-font-lock-mode the terminal buffer also got syntactic fontification, so a quoted string in program output (a diff shown by Claude Code) became font-lock-string-face and overrode the foreground EAT had painted. The result was the theme's string green over the green diff-added background, green on green. I excluded eat-mode the same way dashboard and mu4e are, through cj/exclude-from-global-font-lock. A mode-hook can't do it because global font-lock runs after the mode hook.
