[rafaelcapua]

Description

The Railway CLI is duplicating the output when listing projects.

Commands affected:
• railway list
• railway project list

Both commands print the exact same output twice.

⸻

Environment
• OS: macOS (Apple Silicon)
• Shell: zsh
• Railway CLI version: 4.37.4

⸻

Steps to reproduce
1. Install Railway CLI via Homebrew
2. Run:
railway list or railway project list

Expected behavior

The list of projects should be printed once.

⸻

Actual behavior

The output is printed twice, identically.

Example:

Rafael Yashiki Capua's Projects
Jump Bases
...

Rafael Yashiki Capua's Projects
Jump Bases
...

Additional debugging performed
• Removed all custom .zshrc configuration
• Disabled CLI completion
• Tested using command railway
• Verified no aliases or shell overrides
• Updated CLI to latest version

The issue persists in all cases.

This affects scripting and usability in CLI workflows.
