The installer is idempotent:
- Re-runs safely on every update
- Preserves existing `/etc/hecate/hecate.yaml`
- Automatically migrates legacy defaults (for example `default_budget_seconds: 300` and `runtime_safety_factor: 1.10`)
- Ensures required dependencies are installed (`kubectl`, `nut-*`, `ssh`, `go`, etc.)
- Installs/refreshes systemd units and enables boot-time self-update
- Applies declarative NUT + udev UPS configuration by default (can be tuned via env vars)
