v0.2.0

Second release of farm.query:vgi to Maven Central.

Highlights since 0.1.0

• Expression-filter pushdown — new PushdownFilter.Expression wire decode + PushdownFiltersDecoder rendering pushed expression trees (column refs, constants, functions, comparisons, conjunctions, geoarrow.wkb) to SQL predicates, with FunctionMetadata.withSupportedExpressionFilters(...) capability wiring.
• HTTP transport hardening — the framework's filter / buffering producers are now serializable across the stateless HTTP transport's continuation tokens (no-arg ctors, plain-POJO state, a static storage holder that re-binds on resume). Pairs with vgirpc 0.10.2's state-serialization fixes.
• Integration CI — the upstream vgi sqllogictest suite now runs on every push across three transport lanes (launch, shm, http) against the prebuilt haybarn-unittest + signed community vgi extension.

Depends on farm.query:vgirpc:0.10.2.

Upload is validated by CI but gated on a manual "Publish" click in the Sonatype Central Portal.
