Pin Wasmtime to the Temporal fork revision that provides the experimental store snapshot API. Update the WASM workflow cache snapshot path to use the generic Wasmtime snapshot/restore APIs and preserve the workflow-instance resource representation across rehydration. Extend the sample WASM workflow component with timer-based workflows that exercise snapshot rehydration. Add an explicit WAT-backed funcref table mutation helper and integration coverage that verifies the final component contains table.get/table.set/call_indirect and that the mutated funcref table state survives snapshot restore.
