diagnostics

Snapshot of environment and configuration issues the library has detected — missing iOS Info.plist entries, disabled Android WorkManager, registry not yet sealed, etc. An empty PlatformDiagnostics.diagnostics list (or PlatformDiagnostics.isHealthy == true) means the library believes the environment is correctly configured.

Best-effort per platform — see PlatformDiagnostic for which cases each platform can produce.
