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.

-# If the C compiler in not in ANSI C mode by default, try to add an option
-# to output variable @code{CC} to make it so.  This macro tries various
-# options that select ANSI C on some system or another.  It considers the
-# compiler to be in ANSI C mode if it defines @code{__STDC__} to 1 and
-# handles function prototypes correctly.
-# 
-# If you use this macro, you should check after calling it whether the C
-# compiler has been set to accept ANSI C; if not, the shell variable
-# @code{fp_cv_prog_cc_stdc} is set to @samp{no}.  If you wrote your source
-# code in ANSI C, you can make an un-ANSIfied copy of it by using the
-# program @code{ansi2knr}, which comes with Ghostscript.
