fix(cli): strip -c/--context from extraArgs to prevent git commit conflict

cleye's ignoreArgv passes unconsumed flags and arguments through to
the internal `git commit` execa call. Although -c/--context is
defined as a known cleye flag, a defensive guard is needed to strip
it from extraArgs in case it leaks through, which would conflict
with git's own handling.

Add a sanitization step at the entry of commit() that filters -c,
--context, and their values from extraArgs before they are forwarded
to the git commit invocation.
