CLI displays persistent 'error: too many arguments' message above textbox post-0.4.0 #59

Bug Report

Reported by: bradygaster and multiple other users

Version: Post-0.4.0

Description

After upgrading to 0.4.0 (or later), the CLI displays the error message:

error: too man arguments. expected 0 arguments but got 2.

(and variations of that message) above the textbox in the CLI. The message persists on screen after appearing, consuming valuable screen real estate and degrading the user experience.

Expected Behavior

No spurious error messages should appear above the input textbox. If an argument parsing error occurs, it should be handled gracefully and not persist visually.

Actual Behavior

• The error string appears above the textbox
• It stays on screen (does not dismiss)
• Takes up screen real estate
• Multiple users have reported this independently

Steps to Reproduce

1. Install squad >= 0.4.0 via npx github:bradygaster/squad
2. Use the CLI normally
3. Observe the error message appearing above the textbox

Priority

P1 — visible to all users, degrades experience, reported by multiple people.
