chore!: rename ErrorDispatcherNotFound to EntryFallback

Rename the internal fallback type and its associated `ProgramCollect`
plumbing from `ErrorDispatcherNotFound`/`build_dispatcher_not_found` to
`EntryFallback`/`build_entry_fallback`, along with the generated enum
variant and pack type. Update all documentation, examples, and tests
accordingly.

 > [!TIP]
-> `ErrorDispatcherNotFound` 是 `gen_program!()` 自动生成的类型，代表"没有匹配到任何命令"的情况。为它写 `#[help]` 就是给程序的根命令加帮助。
