add git subsystem — daemon-side status, diff, operations + IPC

Shell-outs to git for status (porcelain v1/v2), unified-diff parsing, and operations (stage, unstage, hunk-apply, discard, commit, stash, log, pull, push). IPC verbs git.* registered on the daemon dispatcher with git.changed event emission on mutations. 42 new core tests. Co-Authored-By: Claude <noreply@anthropic.com>
