cli: exit early for --help/--version without starting app

Browse source 
The CLI previously always started full app initialization (config load, listener
setup, receiver construction, and debug output) even when invoked with `-h`,
`--help`, `-v`, or `--version`. That made basic introspection noisy and buried
the requested output in startup logs.

Add early argument checks in `main()` so help/version requests are handled
immediately and the process exits without starting the app. Introduce a small
`print_help()` helper for consistent usage output.

This improves terminal UX and makes debugging/invocation checks much clearer by
keeping `-h` and `-v` output focused and predictable.
