 * Unified rill CLI entry point.
 * Parses argv[0] as the subcommand name and dispatches to the matching handler.
 * With no subcommand, prints UXT-EXT-11 help and exits 0.
 *
 * Constraints:
 * - Dispatch overhead < 100ms before subcommand body executes (NFR-EXT-5).
 * - `rill help <cmd>` and `rill <cmd> --help` produce equivalent output (FR-EXT-8).
 * - Unknown subcommand: exit 1, error message names the subcommand, prints help hint.
