What's Wrong?

Bug Description

The Bash tool returns "No content" or "Tool ran without output or errors" for all commands, but the commands are not actually being executed.

## Environment

• macOS Version: Darwin 23.6.0
• Claude Code Version: 2.1.17
• Node.js Version: v22.18.0
• Architecture: x86_64 (Intel Mac)

## Symptoms

• All Bash commands return "No content" or "Tool ran without output or errors"
• Commands do not actually execute (no side effects observed)
• Both stdout and stderr are empty/not captured
• Even intentionally failing commands (e.g., ls /nonexistent_path) show the same behavior

## Debug Log Key Error

Shell snapshot file not found after creation

## Steps to Reproduce

1. Run Claude Code on Intel Mac with the environment specified above
2. Execute any Bash command (e.g., echo "test", ls, pwd)
3. Observe that the output is empty and commands don't seem to execute

What Should Happen?

Bash commands should execute and return their stdout/stderr output.
