Problem

There's a security vulnerability in the current implementation where shell commands are being executed without requesting user permission even when in 'suggest' mode. According to our documentation:

In Suggest mode (default): All file writes/patches and ALL shell/Bash commands should require approval.

However, the current implementation in approvals.ts was auto-approving commands deemed "safe" by the isSafeCommand function, bypassing the user permission requirement. This is a security risk as users expect all shell commands to require explicit approval in 'suggest' mode.

Solution

This PR fixes the issue by modifying the canAutoApprove function in approvals.ts to respect the 'suggest' mode policy for all shell commands:

1. Added an early check at the beginning of canAutoApprove to immediately return { type: "ask-user" } when the policy is suggest, regardless of whether the command is considered "safe" or not.

2. Added a similar check in the bash command handling section to ensure bash commands also respect the 'suggest' mode.

3. Updated tests to verify the new behavior, ensuring that all shell commands require approval in 'suggest' mode, while still being auto-approved in 'auto-edit' and 'full-auto' modes when appropriate.

Testing

All tests pass, confirming that the fix works as expected. The updated tests verify that:

• All commands (even "safe" ones) require approval in 'suggest' mode
• Safe commands are still auto-approved in 'auto-edit' mode
• Bash commands with redirects still require approval in all modes

This change ensures that the behavior matches what's documented and what users expect, improving security by requiring explicit permission for all shell commands in the default 'suggest' mode.
