Unused heightBinding parameter breaks embedded placement visibility

High Severity

The selectEmbeddedPlacement function accepts a heightBinding parameter but never uses it. Previously, the onEmbeddedSizeChange callback updated heightBinding.wrappedValue with the new size. Now the onEvent closure is empty. Since the UI only shows the RoktEmbeddedViewWrapper when roktViewHeight > 0 (line 34), the embedded placement will never become visible because roktViewHeight is never updated from its initial value of 0. The same issue applies to the ObjC example where onEvent is empty and [self setupUI:size] is never called.

Local filesystem path dependency in Package.swift

High Severity

The SPM dependency .package(path: "../ROKT/rokt-contracts-apple") references a local filesystem path. This will fail for any consumer resolving this package via SPM, any CI pipeline, or any developer who doesn't have that exact directory structure alongside their checkout. The core SDK's public headers (MPRokt.h, MPKitProtocol.h) now contain @import RoktContracts;, making this a hard build-breaking dependency for all integration methods.
