fix(early-init): stop wiring C-g to the debugger at startup

Setting debug-on-quit t during startup turns C-g into a debugger trigger instead of an abort, so the normal "break out of a hang" reflex drops you into a recursive-edit you can't C-g out of. Worse, debug-on-error is also on during startup. An init error pops the debugger before the emacs-startup-hook cleanup runs, and debug-on-quit stays t for the whole session. I hit exactly that: a quit cascaded into a debugger loop that needed killall to escape.

I dropped debug-on-quit from the startup block and removed its now-redundant cleanup line. debug-on-error stays on during startup so init errors are still caught. C-g stays an escape hatch.
