   ## What changes were proposed in this PR?
   
   Common  cases for all four newly-wired predicates follow the same pattern as 
from the ST_Contains foundation:
     - Coarse filter is the JTS STR-tree on lat/lng envelopes (with 
antimeridian → full-longitude wrap), built once per broadcast.
     - S2 ShapeIndex caching is lazy on the build-side WKBGeography instances — 
first refinement query builds the index, subsequent queries reuse it.
     - Without a broadcast hint and with autoBroadcastJoinThreshold=-1 (test 
default)
   
   For ST_DWithin: 
     - Build-side index: New toExpandedGeographyEnvelopeRDD: using 
Haversine.expandEnvelope(env, distance, polarRadius=6_357_000m) with 10% margin 
& pole-snap. 
     - Per-row distance carried in GeographyJoinShape.radius.
     - Stream-side shape: New stream branch in createStreamShapes: same 
expansion, same GeographyJoinShape(geog, row, radius) payload.
     - Refiner: GeographyDistanceRefiner(swap) → Functions.dWithin(a, b, 
streamRadius) (S2 closest-edge query).
   
   ## How was this patch tested?
   New tests are added for each join type
   
   ## Did this PR include necessary documentation updates?
   
   - No, this PR does not affect any public API so no need to change the 
documentation.
