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.

-#!/bin/sh
-# airplane-mode — toggle a low-power "airplane" state for a laptop.
-#
-# Engage: record the current state of each lever, then apply low-power values:
-#   - wifi off (nmcli; bluetooth is left alone, on purpose — earbuds)
-#   - CPU energy-performance preference -> power (intel_pstate, via sysfs)
-#   - display brightness dimmed
-#   - stop network-only services (VPNs, sync, discovery, inbound SSH)
-# Disengage: read the recorded state and restore exactly what was there. A
-# lever already in its low-power position before engaging (e.g. wifi already
-# off, a service already stopped) is left untouched on disengage.
-#
-# State lives at $XDG_RUNTIME_DIR/airplane-state as key=value lines. The
-# waybar-airplane indicator reads `mode` from it.
-#
-# Env knobs (defaults are the real system; tests override them):
-#   AIRPLANE_EPP_GLOB        glob of EPP sysfs files
-#   AIRPLANE_BRIGHTNESS_LOW  brightnessctl target while engaged
-#   AIRPLANE_SYSTEM_SERVICES system units to stop (sudo)
-#   AIRPLANE_USER_SERVICES   --user units to stop
