v0.1.0-alpha.10

Fix LyraCore Operator cleanup against the durable Account ownership API. Structured GUID fields are JSON numbers, preserving the decimal digits without float conversion. Release alpha9 encoded them as JSON strings, which the Module refuses.

Legacy reducer calls remain compatible. All four offline shell suites, Linux/macOS tests and coverage CI pass. A real SpacetimeDB 2.7.1 call preserves GUID 9007199254740993 exactly.
