Remove rhiza welcome command

[Copilot]

rhiza welcome was a dedicated command that only printed a static ASCII-bordered banner — information already covered by rhiza --help. Deleted the command and all associated code.

Changes

• src/rhiza/commands/welcome.py — deleted entirely
• src/rhiza/cli.py — removed welcome_cmd import and the @app.command() welcome() function
• tests/test_cli_commands.py — removed TestWelcomeCommand class and its three test methods

Original prompt

Summary

Remove the rhiza welcome command as a simplification. It is a 62-line file that does nothing except print() a static ASCII-bordered welcome message — information that duplicates rhiza --help. A dedicated command for a static text banner is unnecessary complexity.

Changes required

1. Delete src/rhiza/commands/welcome.py

Delete the file entirely. It contains a single function welcome() that only prints a hardcoded multi-line string.

2. Update src/rhiza/cli.py

• Remove the import on line 23:

  from rhiza.commands.welcome import welcome as welcome_cmd

• Remove the entire welcome CLI command (lines 388–398):

  @app.command()
  def welcome() -> None:
      r"""Display a friendly welcome message and explain what Rhiza is.
  
      Shows a welcome message, explains Rhiza's purpose, key features,
      and provides guidance on getting started with the tool.
  
      Examples:
          rhiza welcome
      """
      welcome_cmd()

3. Update tests/test_cli_commands.py

Remove the entire TestWelcomeCommand class and its three test methods:

• test_welcome_command
• test_welcome_command_function_coverage
• test_welcome_cli_wrapper_coverage

These tests exclusively test the welcome command and welcome.py module being deleted.

Notes

• No other files import from rhiza.commands.welcome — only cli.py and the test file.
• The commands/__init__.py does not import welcome, so no change is needed there.
• This is a pure deletion/cleanup — no replacement behaviour is needed. Users wanting an overview of the tool should use rhiza --help.
