refactor: drop in-repo dotfiles/, move stow tooling to the dotfiles repo

Since the installer clones DOTFILES_REPO into ~/.dotfiles and stows from there, the in-repo dotfiles/ tree was dead weight. Nothing reads it at install time. I removed it (831 files) now that both machines are migrated.

The Makefile's stow / restow / reset / unstow / import targets and the dotfile-script unit suites moved to the dotfiles repo. They sit alongside the scripts they manage and run standalone (cd ~/.dotfiles && make ...). This Makefile keeps the VM-integration targets and the installer-helper suite (safe-rm-rf).

I updated CLAUDE.md and README.md so stow operations run from ~/.dotfiles, and the dotfile-management, theme, and unit-test sections point at the standalone repo. The README was already describing the old in-repo model from before the installer switched to cloning. This brings it in line.
