macOS path_helper runs after .zshenv and can move system Python ahead of pyenv. Add an idempotent login hook and preserve it across later easyzsh migrations.
The pyenv fragment lived in the interactive overlay, so agents and zsh -c fell back to system Python. Install it through the always-on fragment path and keep XDG destinations aligned with the loader.
fnm lived in interactive-only ~/.config/zshrc, so ssh/agents/zsh -c
missed fnm-managed node. Source ~/.config/zsh/*.zsh from .zshenv and
install the fragment as zsh/fnm instead.
