Fix incorrect CVE reference for core.fsmonitor, clarify bash/zsh
compatibility (shebang is bash, works from zsh sessions), fix -y mode
signing behavior to not break commits when no key exists, clarify
submodule.recurse scope, add pull.rebase conflict warning, improve
SSH config and credential helper detection specifics, add FIDO2
touch prompt, and clarify audit exit code for missing signing keys.
