fix: int32→int64 for BSON property values, CREATE OR REPLACE PAGE UUID reuse
BSON int32→int64: - All property values in writer serialization changed from int32 to int64 to match Studio Pro's expected BSON types - Array version markers (int32(2), int32(3)) preserved as int32 - Fixes Studio Pro crash: "Sequence contains no matching element" in MprProperty..ctor when type cache expects int64 but finds int32 CREATE OR REPLACE PAGE: - Reuses existing page UUID and calls UpdatePage instead of DeletePage+ CreatePage, producing git "Modified" diff instead of "Deleted+Added" - Prevents RevStatusCache crash when parsing deleted mxunit base files BSON roundtrip test baseline: - Add golden mxunit files for roundtrip testing (pages, microflows, enums) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
