upstream(swift): track WasmKit public resource-control release

[enricopiovesan]

Summary

Track the upstream WasmKit release required for the Swift embedder to enforce bounded memory and deterministic interruption through public APIs.

Governing context

• Spec 074 and Apple: ship public Swift embedder SDK for iOS and macOS clients #647
• ADR-0011

Definition of Done

• A released WasmKit version exposes documented public, non-SPI bounded-memory controls.
• The release exposes documented public, deterministic interruption/cancellation controls.
• The Swift embedder records the exact WasmKit version and API evidence.
• Physical iOS and macOS certification fixtures pass for memory bounds and interruption.
• Apple: ship public Swift embedder SDK for iOS and macOS clients #647 is updated or unblocked with that evidence.

Validation

Run the physical-device fixture matrix and link versioned upstream API documentation.

Non-goals

Using SPI, watchdog workarounds, or changing the upstream API contract.
