• Cache permission results (@tg-msft)
• Remove unnecessary nil checks before range (@tg-msft)
• Use glob matching library (@tg-msft)

What needs to change

1. Caching: Add caching to the permissions service — permissions are unlikely to change during an azd session.
2. Nil checks: Remove unnecessary nil checks before range statements — range over a nil slice is a no-op in Go.
3. Glob matching: Consider using a glob matching library instead of the custom wildcardMatch implementation to avoid maintaining custom logic if assumptions change.
