Always-on and machine hooks already live in .zshenv / local.zsh.
Drop the empty stub, remove it on deploy, and leave real .zprofile
files to optional migration into local.zsh only.
Drop ~/.config/zsh/{env,interactive,login} modules. PATH and local.zsh
live in .zshenv; interactive UX is a single .zshrc again. Deploy only
installs the three stubs and removes obsolete trees/examples.
Replace the local/ directory of split env/login/interactive files with
one always-on local.zsh sourced from .zshenv. Deploy migrates old
fragments and never overwrites local.zsh.
Split always-on PATH/env, login hooks, and interactive UX into a
managed tree under ~/.config/zsh, with never-overwrite local/ hooks.
Agents and interactive shells share one PATH owner; deploy.sh applies
the layout safely across machines.
