Package actions orchestrates the high-level watchtower update flow: listing containers, running sanity and duplicate-instance checks, and driving the stop/start sequence through pkg/container.

Package events bridges Docker engine image events to targeted watchtower scans, so local `docker build` / `docker load` rebuilds trigger an update without waiting for the next scheduled poll.

Package flags defines watchtower's CLI flag set and the viper-backed environment-variable bindings that accompany it.

Package meta holds build-time metadata populated via -ldflags.

Package util contains small utility helpers shared across watchtower.
