Why

Several bridge fixes merged without a test (#5, #7, #8, #9, #11), so nothing stops them from coming back. 0.3.0 already regressed one earlier fix in the Android serializer (#13). These tests pin each fix to the payload the native bridges send today, so a test both documents the contract and catches a regression.

Stacked on #13. This branch contains #13's two fix commits and its harness commit (the ci~/android-harness/bridge-tests source set and the native.yml step). Review or merge #13 first; this PR then reduces to the last commit.

Changes

C# (Tests/Runtime/BridgeRegressionTests.cs):

• Fix SubscriptionStatus property dropping entitlements in both directions #5 - SubscriptionStatus keeps its entitlements read from native (subscriptionStatusDidChange) and written to native (the setter's payload, read from the Editor log of the native call).
• Fix SuperwallEventInfo.EventType never matching the enum, and add the missing EventType members #7 - SuperwallEventInfo.EventType parses Android snake_case (transaction_complete, freeTrial_start), iOS camelCase, and the two remapped names (deepLink_open, paywallWebviewLoad_processTerminated).
• Carry product, transaction and paywall info on delegate events #9 - delegate events carry Product, Transaction and PaywallInfo, and leave them null when the payload has none.
• Parse StoreProduct prices culture-invariantly (Android sent 199.99 as 19999 on pt-BR devices) #11 - product prices parse the same under pt-BR, whether they arrive as strings (Android) or numbers (iOS).
• Serialize every Entitlement field on both native bridges #8 (C# side) - an entitlement with all 13 fields deserializes in the shared vocabulary (playStore, inGracePeriod, inBillingRetryPeriod, trial), and an Android-only offer type (subscription) stays null.

Kotlin (ci~/android-harness/bridge-tests, run by native.yml):

• Serialize every Entitlement field on both native bridges #8 (Android side) - serializeEntitlement emits every field in the C# vocabulary, maps GRACE_PERIOD / BILLING_RETRY to the C# names, omits absent optionals, and drops UNKNOWN.

Runtime test assembly made runnable. Superwall.Tests.asmdef was restricted to the Editor platform, so its [UnityTest]s ran in EditMode, where BridgeCallbackHandler.Initialize calls DontDestroyOnLoad and throws. All 33 tests failed in EditMode, and PlayMode found none. The assembly now targets all platforms and runs in PlayMode. It is still compiled only with UNITY_INCLUDE_TESTS, so player builds are unaffected. Two existing tests asserted DoesNotThrow on payloads that the handler reports with an error log. They now expect that log, because Unity fails a test on any unexpected error.

Verification

• C#, PlayMode, Unity 6000.5, in a throwaway project that loads this checkout as a local package with "testables": ["com.superwall.sdk"]: 33/33 pass.
• The tests catch the regressions they guard. With the culture-dependent price parse and the setter that drops entitlements restored, the price test and the setter test fail (2 failures, all others pass).
• Kotlin, AGP 8.5.2: 7/7 pass (4 new plus Preserve entitlements in Android subscription status #13's 3). The AGP 9.0.1 job has only run in CI.
• unity.yml is still parked, so CI does not run the C# tests yet. The local recipe above is what this PR used.

Not covered (no harness exists for it)

The Swift halves of #3 (event-param sanitizer), #6 (onDismiss product id), #7, #8 and #9. Proposal: add an XCTest target to ci~/ios-harness/Package.swift and an xcodebuild test step with an iOS Simulator destination in native.yml; the bridge's serializers would need internal visibility for @testable import. I have no macOS machine to build and run it on, so it is not part of this PR.
