librelad 7988778f73 refactor(task): move processor out of crontab/ + launch via stable CLI entry
The task processor is a systemd-service daemon, not a cron job — move it out
of the misleadingly-named scripts/crontab/task/ to scripts/task/.

To stop the systemd unit from baking the processor's in-tree path (the footprint
coupling that forces a reinstall on every reorg), the unit now ExecStarts the
stable wrapper: /usr/local/bin/libreportal __task-processor. start.sh intercepts
that early (after paths.sh, before the heavy load), exports install_scripts_dir,
and exec's the processor with start_script. Future moves/renames need only the
one hand-off updated + a regen — no footprint bump.

- git mv scripts/crontab/task -> scripts/task (filenames kept; cron-watchdog grep
  + function names unchanged)
- libreportal-svc: ExecStart -> stable wrapper launcher
- start.sh: __task-processor internal launcher (export install_scripts_dir; exec)
- crontab_task_processor.sh: fix self-location ../.. -> .. for the new 1-level
  depth (latent bug the move would otherwise have introduced)
- regen files_*/function_manifest; add task_scripts to the app/cli aggregates
- footprint_version 3 -> 4 (root-owned svc unit changed -> needs a root reinstall)

# LibrePortal Task Processor Systemd Service Setup
# Replaces crontabSetupTaskProcessor with systemd service.
#
# Idempotent: computes the desired unit for the CURRENT docker mode and only
# rewrites + daemon-reloads + restarts when it actually differs from what's on
# disk. So routine re-runs are no-ops (no needless restart that would kill an
# in-flight task), while a rooted<->rootless switch — which changes the env
# block — triggers exactly one rewrite + restart so the processor re-reads the
# new mode. Safe to call from install AND from the docker-type switcher.
