Providers

Providers are adapters that deliver analytics events to specific backends. They implement a stable interface so application code never depends on a vendor SDK directly.

Provider error semantics

Providers that don't support an operation return ErrUnsupportedOperation — they never silently no-op. This prevents data from appearing delivered when it was actually discarded.
