Add git-identity: switch git author identity from a saved menu
Identities live in ~/.git-identities (alias|Name|email). Interactive menu to select, add, or remove identities; direct mode via alias argument; --global/-g scope flag (defaults to local inside a repo, global fallback outside); --list/--current helpers. Full --dryrun support and a 27-assertion test suite driven through dryrun. GIT_IDENTITIES_FILE env override for testability.
