fix(cli): lifecycle tools in HM so stale pull can self-heal

Extract nomarchy-pull/rebuild/home to pkgs/nomarchy-lifecycle; install
via system + home. Home profile wins on PATH so home-manager switch
installs the fixed pull (skip git when no upstream) without waiting
for a system rebuild that needed a working pull first.

V0: flake check --no-build green.
