Stability

• Stable — createIAP, IAP interface methods, all EntitlementBase / Product / PurchaseResult / RestoreResult types, every IAPErrorCode value, every event in EventMap. These follow semver.
• Stable but advanced — BackendAdapter, HttpBackendAdapter, HttpClient. Public so non-HTTP transports can be implemented; we reserve the right to add new methods to BackendAdapter in minor versions (additive only).
• Internal — anything not listed in src/index.ts is private. Don't import from deep paths.
