@spec exec([String.t()]) :: term()

Runs a single command without re-starting the application stack.

This is the in-process execution path used by alaja action for batch execution. It assumes the application is already running, so it skips Application.ensure_all_started/1. Use main/1 for the top-level entry point and exec/1 for child invocations.

Example

Alaja.CLI.exec(["message", "--text", "Hello"])

Runs the CLI with the given arguments.
