dotfiles

Onboard a new machine into the dotfiles fleet. Use when the user mentions a new PC/laptop they want to share configuration with, or asks to "set up dotfiles on a new machine".

Push local dotfiles changes to all four hosts (local, home, home2, ep). Use when the user says "deploy this", "push to other hosts", "他のPCにも反映", or after committing changes that need to land on remote machines.
