system temp directory should add to allowed list for file access

[doggy8088]

Describe the bug

The recent version of Copilot CLI appears to block access to the TEMP directory, which was previously allowed.

Affected version

0.0.340 Commit: fac8111

Steps to reproduce the behavior

I'm using Windows 10 with Windows Terminal with PowerShell 7 (pwsh.exe).

1. Create a C:\TEMP1 folder.

2. Change working directory to C:\TEMP1.

3. Create a test.ps1

   echo '❌ An error occurred, please check the detailed log at: C:\TEMP\err.log'
   echo '❌ An error occurred, please check the detailed log at: C:\TEMP\err.log'

4. Create a err.log to your $env:TEMP folder (I assume it's C:\TEMP folder) which is normally allowed by Copilot CLI.

5. Run the following command:

   copilot --allow-all-tools -p 'Run test.ps1'

6. You will see the following:

   ✓ Run test.ps1 script
   $ .\test.ps1
   ↪ 3 lines...
   ● The script ran but produced error messages. Let me check what's in the error log and the script
   itself to understand what happened.
   
   ✓ Read test.ps1 (7 lines)
   
   The following paths are outside the allowed directories:
   - C:\TEMP\err.log
   
   Allow access to these paths? (y/n):

Expected behavior

I expected to access any files in the TEMP folder without needing permission.

Additional context

• Operating system: Windows
• CPU architecture: x86_64
• Terminal emulator: Windows Terminal

We've added the temp directory to the default allowed directories in 0.0.349! Thanks for the feedback
