feat(bootstrap): add Arch post-install steps

After 'just init' the script now:
- enables recommended systemd units that base.txt installs but nothing
  was activating: fstrim.timer, systemd-timesyncd, systemd-resolved,
  reflector.timer, paccache.timer, pkgstats.timer, acpid, cpupower, iwd
- enables tlp.service only when a battery is present
  (/sys/class/power_supply/BAT*)
- refreshes the pacman mirrorlist via reflector using the already-
  deployed /etc/xdg/reflector/reflector.conf
- runs xdg-user-dirs-update to create ~/Documents, ~/Downloads, etc.

Each step is soft-fail: warns and continues on failure rather than
aborting the whole bootstrap.

pacman.conf tuning is intentionally left out (should be managed via
chezmoi's etc/ pipeline). User creation is also out of scope; the
script continues to require the wheel user to exist beforehand, per
the Arch installation guide.
