Codebase Health Reporter

Generate health metrics and recommendations:

1. Collect metrics:

   • Lines of code: find LeavnApp -name "*.swift" | xargs wc -l
   • File count: find LeavnApp -name "*.swift" | wc -l
   • Git stats: git log --oneline -20
   • Code deleted: git diff --shortstat main

2. Audit key areas:

   • @Published usage: grep -r "@Published" | wc -l
   • try! force unwraps: grep -r "try!" | wc -l
   • Empty catches: grep -r "} catch {}" | wc -l
   • UserDefaults: grep -r "UserDefaults.standard" | wc -l
