Permission 'don't ask again' not persisting across sessions

Description

When selecting "Yes, and don't ask again for [command] in [project]" during a permission prompt, the setting does not persist across sessions. Users are prompted again in each new session despite having the permission already saved in .claude/settings.local.json.

Steps to Reproduce

1. Run a command that triggers a permission prompt (e.g., gh pr create)
2. Select "Yes, and don't ask again for gh pr create commands in /path/to/project"
3. Verify the permission is added to .claude/settings.local.json (it is)
4. Start a new Claude Code session
5. Run the same command again
6. Actual: Permission prompt appears again
7. Expected: Command runs without prompting since permission is in settings file

Environment

• The permission Bash(gh pr create *) is correctly present in .claude/settings.local.json
• Issue persists across multiple sessions

Expected Behavior

Permissions saved via "don't ask again" should be respected in subsequent sessions when the pattern matches the command being run.
