xh.nu completion script causes parser error on --generate flags in Nushell (nu::parser::missing_positional)

Describe the bug

When sourcing the generated Nushell completion script (xh.nu) via use xh.nu *, executing valid commands like xh --generate man fails at the Nushell parser level with Error: nu::parser::missing_positional.

This happens because the parameter definition in xh.nu marks raw_method_or_url as a required positional argument, which prevents Nushell from parsing subcommands/flags that do not expect a URL or method argument.

To Reproduce

1. Generate the Nushell completion script: (Under bash)

   bash复制

   xh --generate complete-nushell > ~/.local/share/nushell/completions/xh.nu 

2. Import the completion module in Nushell:

   nushell复制

   use xh.nu *

3. Run any --generate command:

   bash复制

   xh --generate man

Expected behavior

The command xh --generate man should successfully output the man page documentation without being blocked by Nushell's parameter parser.

Actual behavior

Environment

• OS: Rocky Linux 10.2
• XH version:
  bash复制

  $ xh --version
  xh 0.26.2
  -native-tls +rustls

• Nushell:
