A pass over the install scripts, dev-tools commands, and Hyprland Lua
files that I had stuffed with explain-everything preambles. Most of
those rationales (which files ship where, why hyprctl setenv doesn't
suffice, etc.) belong in commit messages or PR descriptions, not in
code people have to read forever. Kept the few comments that document
genuinely non-obvious behaviour: the keybind-env reason for hl.env in
envs.lua, why the runtime PAM seds stay scripted in
increase-lockout-limit, the chroot/--now distinction in chroot.sh, and
the dev-pkg-test split-install reason.
Each script's static-file write moves to omarchy-settings. The scripts
keep only the runtime side: reload systemd, restart dirmngr, sysctl --system,
or (for lockout-limit) the PAM seds that have to stay scripted because
/etc/pam.d/system-auth and /etc/pam.d/sddm-autologin are upstream-owned and
need targeted line edits rather than a full-file override.
faillock.conf's deny=10 (formerly inside increase-sudo-tries.sh sed) now
rides through the etc-overrides dance in omarchy-settings.
