Foundation for a scoped sudoers: route every genuine system-admin command
(systemctl/ufw/ufw-docker/nft/apt/apt-get/pacman/sysctl/useradd/usermod/
service/wg/wg-quick/cscli/loginctl) through runSystem instead of raw sudo
across 28 active scripts. runSystem is 'sudo "$@"' so this is byte-identical
in every mode (safe on live installs) — it just collects all real-root use at
one chokepoint that will define the eventual /etc/sudoers.d allowlist.
Also: revert a crowdsec advice message the sweep wrongly rewrote (the admin
types sudo, not runSystem), and give crontab_check_processor.sh the same
startup bootstrap as the task processor — it runs standalone via cron and
already used runFileOp/runFileWrite (undefined there), so it was silently
broken; now it sources the helpers + docker-type config.

The 'Update the .bashrc file' step printed its header but, when the rootless
block was already present, the if-guard skipped the whole body with no output
— looked like nothing happened. Add an else that notes it's already configured.

Disabling userland-proxy makes rootless dockerd require br_netfilter
(/proc/sys/net/bridge/bridge-nf-call-iptables), absent in the rootless
netns on Debian -> default bridge creation fails -> daemon won't start.
Drop the daemon.json userland-proxy=false write. Source-IP is preserved
at L7 by Traefik (X-Forwarded-For), so no real loss.

Reinstall test on Debian 12 surfaced three rootless-only breakages (rooted
was byte-identical/fine):
1. pasta blocked by Debian's passt AppArmor profile (DENIED ptrace read ->
can't open container netns -> rootless dockerd never starts). Default
CFG_ROOTLESS_NET back to slirp4netns (reliable); pasta stays selectable
for hosts that relax the profile.
2. de-sudo mis-assigned helpers by owner. /docker management layer (apps DB
chowned to libreportal by install_sqlite, /docker/logs) is MANAGER-owned,
not dockerinstall. Add runInstallWrite; move apps-DB sqlite3 -> runInstallOp
and /docker/logs appends -> runInstallWrite. Revert ownership-SETUP scripts
(libreportal_folders, app_folder) to runSystem — they must run as root to
establish ownership during install. Container files (/docker/containers/<app>)
stay runFileOp.
3. kernel hardening sysctls written to /etc/sysctl/99-custom.conf, which
'sysctl --system' does not read -> never applied. Write them to
/etc/sysctl.d/99-libreportal-hardening.conf instead.

Enabling unprivileged user namespaces for rootless widens the kernel
attack surface reachable by unprivileged users (a known source of LPE
CVEs). Pair it with three distro-portable, low-impact sysctls that close
the surfaces those exploit chains rely on: kernel.kptr_restrict=2 (hide
kernel pointers), kernel.yama.ptrace_scope=1 (block cross-process
ptrace), net.core.bpf_jit_harden=2 (harden the JIT). Added as a separate
guarded LIBREPORTAL KERNEL HARDENING block so it's clearly deliberate and
independently idempotent.

Switch the rootless network stack from slirp4netns+builtin to pasta+
implicit (faster and propagates the real client source IP). The earlier
pasta+builtin attempt bricked the daemon because rootlesskit rejects
mismatched net/port-driver pairs; expose a single CFG_ROOTLESS_NET knob
(pasta default, slirp4netns fallback) and derive the matching port
driver in-script so an invalid combo can't be configured. Disable
userland-proxy in the rootless daemon.json (merged, not clobbered) so
containers see the real source IP. Both driver binaries are always
installed, so switching is a config flip + rootless re-setup.

The rootless dockerd override forced NET=pasta + PORT_DRIVER=builtin, which
rootlesskit rejects ('pasta requires port driver none or implicit'), so the
daemon failed to start every time (the real cause behind 'rootless socket not
found'). Use slirp4netns + builtin (valid, still skips the userspace
port-handler). Verified: daemon now comes up, docker Server 29.5.2 responds.

useradd was missing its login-name argument (and -m), so it failed — silently,
because local result=$(...) swallowed the exit code and checkSuccess reported
success. The rootless install user was therefore never created, which cascaded
into 'invalid user dockerinstall' and a daemon that never came up. Pass the
username + -m (subordinate uid/gid ranges come from login.defs), unmasked.
