Bash wildcard permissions in settings.local.json not matching commands

Description

Wildcard permission patterns like Bash(az *) in .claude/settings.local.json do not match commands. Each command still triggers a permission prompt, and the exact command string gets appended to the allow list instead of being matched by the existing wildcard.

Reproduction

1. Create .claude/settings.local.json:

{
  "permissions": {
    "allow": [
      "Bash(az *)",
      "Bash(gh *)",
      "Bash(git *)",
      "Bash(curl *)"
    ]
  }
}

1. Ask Claude to run a command like az containerapp show --name foo --resource-group bar
2. Expected: Command auto-allowed by Bash(az *) wildcard
3. Actual: Permission prompt appears. Clicking "Always allow" appends the exact command string to the allow list

Evidence

After a session, the settings file grows from 4 wildcard rules to 30+ exact-match entries:

{
  "permissions": {
    "allow": [
      "Bash(az *)",
      "Bash(gh *)",
      "Bash(az acr list --resource-group rg-foo --query \"[0].name\" -o tsv)",
      "Bash(az containerapp logs show --name bar --resource-group rg-foo --tail 30)",
      "Bash(gh variable list -R owner/repo)",
      "..."
    ]
  }
}

The wildcards on lines 1-2 should have matched all of these.
