`uninstall` / `uninstall --purge` previously removed services and (on
purge) `rm -rf`'d a hand-maintained list of paths with no output, so users
could not see what would be — or had been — deleted (TC-MAC-026).
Add a pre-flight `print_uninstall_summary` that lists the apps/services to
be removed (launchd agents on macOS; systemd units + docker containers on
Linux) and, when --purge is set, every target path with its current
[present]/[absent] status. Centralize the purge paths into a single
source-of-truth inventory and route deletions through a `purge_path`
helper that prints `removed:` / `absent (skipped):` per path. Document the
subcommands in the usage header. Behavior is otherwise unchanged.
