fix(cli): strip -y/--fgm from extraArgs to prevent git commit conflict

Same class of bug as the -c/--context fix: these flags could leak
into extraArgs and be forwarded to the internal `git commit` call,
causing unexpected behavior.

Extend the extraArgs sanitization to also strip -y, --yes, --fgm,
and their values.
