ArrTop
arrtop — a top-like terminal UI for the Sonarr/Radarr download + import
pipeline. It reads the *arr queue (typed, via the sonarr/radarr shards),
sorts by what's actively importing, and renders progress bars — including
import (copy) progress the *arr API does not report, read from the destination
file on disk. That disk read means arrtop is meant to run *on the arr host.
Constants
Class methods
Configures Crystal's Log for arrtop. Logs go to STDERR so the future
TUI can own STDOUT for its rendering.
The level is pinned to Info for now — the CLI calls this with the default.
Making the level configurable (via a CLI flag, an env var, or the config
file) is deferred to a later phase; the level parameter already threads
through so that wiring is a small change when it lands.
