good first issue

描述

Today, we have re-routed all four forms of help to only show the short help, the default clap provides on -h.

Instead, let's provide both long and short help, like this:

  • Global -h on any command, like rv ruby pin -h: show short help
  • Global --help on any command, like rv ruby pin --help: show short help
  • rv help [NAME], like rv help ruby pin: show long help
  • rv NAME help, like rv ruby help pin or rv ruby pin help: removed, it's confusing to have many help commands

研究方向
The issue requires modifying the help routing logic in the CLI entry point (likely `src/main.rs`). Currently, all help forms show short help. You need to implement long help (with full descriptions) for `rv help [NAME]` and remove the `rv NAME help` variant. Examine the clap App setup and the existing help commands to understand the current flow.
