[BUG] CPU 100% usage by npm view command loop

Environment

• OS: Ubuntu 22.04 LTS
• Claude Code Version: 1.0.100
• Node.js Version: v22.17.0
• Server Specs: 4GB RAM, 4 CPU cores
• Date: 2025-09-03

Issue Description

Claude CLI repeatedly executes npm view @anthropic-ai/claude-code@latest version in an infinite loop, causing 100% CPU usage and making the server unresponsive.

Reproduction Steps

1. Start Claude CLI session with claude command
2. Monitor system processes with top or ps aux
3. Observe npm view @anthropic-ai/claude-code@latest version process consuming 100% CPU
4. Kill the process with pkill -f "npm view"
5. Process immediately restarts and continues consuming 100% CPU

Expected Behavior

Version check should:

• Run once at startup, or
• Run at reasonable intervals (e.g., once per hour/day)
• Not consume excessive CPU resources

Actual Behavior

• Version check runs continuously in an infinite loop
• Process consumes 100% CPU
• Server becomes unresponsive
• Killing the process results in immediate restart
• Multiple instances may spawn simultaneously
