Parent: #989
Depends on #991 + #994. Parses the WKT-encoded initial-default / write-default into WKB at metadata-load time (using the helper added in #991) and applies them via the existing default-value enforcement (#820). The write path routes records through the partition writer by transform — only identity is defined for geo today, but plumb so future bbox-bucket transforms drop in.
Tests write a table with a geometry column and verify Parquet GeoStatistics + manifest bounds are populated end-to-end. Cross-client read by Java pins the wire format.
