chezmoi-management

@mizchi

Meta-skill for mizchi's chezmoi dotfiles. Invoke ONLY when the user explicitly asks to manage / diff / apply chezmoi sources, add a skill to dotfiles, audit the APM vs chezmoi boundary, or initialize a new machine. Covers source location, diff/apply flow, skill addition, pre-push (pkfire + secretlint). Do NOT auto-invoke when the task only happens to touch a path under ~/.claude/, ~/.config/, or ~/.zshrc — consult only on explicit dotfile-management intent.
