test(sdk): use stable reconcile request type

[alongubkin]

Summary

• deserialize the generated SyncReconcileRequest in the SDK round-trip test
• avoid referencing the removed inline SyncReconcileRequestState type after model deduplication

Validation

• this is the focused fix from local commit b2b40f402 for the E0425 release-PR failure
• git diff --check

Linear: ALIEN-525

[alongubkin]

Admin-merging to unblock v3.3.14 qualification. This is the focused stale generated-type test fix already validated in local commit b2b40f4; release PR #431 currently fails because it does not include it.

Greptile Summary

This PR updates the Rust platform SDK round-trip test to deserialize through the stable generated SyncReconcileRequest type after model deduplication.

• Wraps the existing deployment-state fixture with a valid deployment ID.
• Serializes the generated request’s state and retains the runtime-update metadata assertions.

Confidence Score: 5/5

The PR appears safe to merge because the focused test-only change supplies all required request-level fields and preserves the existing metadata assertions.

The change replaces a removed inline generated type reference with deserialization through the stable request model, and no concrete build, serialization, or runtime failure remains established.

Important Files Changed

Filename	Overview
client-sdks/platform/rust/src/lib.rs	Updates a test to exercise the stable generated reconcile-request type without changing production behavior; no actionable defect was established.
