Deliver end-to-end native monitoring path under runit with existing
CLI/TUI controls and truthful status, preserving systemd behavior.
Changes:
- Add init system abstraction layer (src/fenris/init_system.py) that
detects systemd vs runit and provides unified interface for timer
control, on-demand collection, and service state queries
- Create runit service files (units/runit/) with completion-relative
5-minute cadence, 2-minute boot delay, bounded execution (90s),
no catch-up, and serialized runs via flock
- Update monitor.py to use abstraction layer instead of direct systemctl
- Update status.py to use abstraction layer for service state queries
- Update all packaging scripts (deb, rpm) for init-system-aware setup
- Update Makefile to install runit service files alongside systemd units
- Add 46 tests for init system abstraction layer
