refactor!: replace sys-systemctl with sys-service, add sys-daemon, and rename systemctl_* → system_service_* across repo 
- Swap role includes: sys-systemctl → sys-service in all roles
- Rename variables everywhere: systemctl_* → system_service_* (incl. systemctl_id → system_service_id)
- Templates: ExecStart now uses {{ system_service_script_exec }}; add optional RuntimeMaxSec via SYS_SERVICE_DEFAULT_RUNTIME
- Move SYS_SERVICE defaults into roles/sys-service/defaults (remove SYS_SERVICE_ALL_ENABLED & SYS_SERVICE_DEFAULT_STATE from group_vars/07_services.yml)
- Tidy group_vars/all/08_timer.yml formatting
- Introduce roles/sys-daemon:
  - default manager timeouts (timeouts.conf)
  - optional purge of /etc/systemd/system.conf.d
  - validation via systemd-analyze verify
  - handlers for daemon-reload & daemon-reexec
- Refactor sys-timer to system_service_* variables (docs and templates updated)
- Move filter_plugins/filetype.py under sys-service
- Update meta/README to point to official systemd docs
- Touch many roles (backup/cleanup/health/repair/certs/nginx/csp/wireguard/ssd-hdd/keyboard/update-docker/alarm compose/email/telegram/etc.) to new naming

BREAKING CHANGE:
- Role path/name change: use `sys-service` instead of `sys-systemctl`
- All `systemctl_*` vars are now `system_service_*` (e.g., on_calendar, state, timer_enabled, script_exec, id)
- If you have custom templates, adopt RuntimeMaxSec and new variable names

Description

Role to manage systemd service units for Infinito.Nexus software stacks.
It installs or removes unit files, configures runtime behavior, and ensures services are properly deployed.

Overview

  • Resets service units by removing old or obsolete definitions.
  • Deploys new service unit files and service scripts.
  • Optionally sets up timers linked to the services.
  • Ensures correct reload/restart behavior across the stack.

Features

  • Unit Cleanup: Automated removal of old service units.
  • Custom Templates: Supports both systemctl.service.j2 and systemctl@.service.j2.
  • Timers: Integrates with sys-timer for scheduled execution.
  • Runtime Limits: Configurable RuntimeMaxSec per service.
  • Handlers: Automatic reload/restart of services when definitions change.
