Register three MEOS-backed function overloads needed for portable BerlinMOD queries: - overlaps_tspatial_tspatial → &&(TGEOMPOINT, TGEOMPOINT) - nad_tgeo_tgeo → nearestApproachDistance(TGEOMPOINT, TGEOMPOINT) - tspatial_to_stbox + stbox_expand_space → expandSpace(TGEOMPOINT, DOUBLE)

Summary
Adds three MEOS-backed functions that complete BerlinMOD portable SQL coverage on MobilityDuck:
nearestApproachDistance(TGEOMPOINT, TGEOMPOINT) → DOUBLE— wrapsnad_tgeo_tgeo; returns NULL (not 0) when trips have no overlapping time extent (sentinelDBL_MAX→ SQL NULL viaExecuteWithNulls)expandSpace(TGEOMPOINT, DOUBLE) → STBOX— wrapstspatial_to_stbox+stbox_expand_space; enables thetrip && expandSpace(other, dist)index pre-filter in Q10&&(TGEOMPOINT, TGEOMPOINT) → BOOLEAN— wrapsoverlaps_tspatial_tspatial; STBox overlap pre-filter for cross-trip joinsBerlinMOD impact:
nearestApproachDistanceexpandSpace16/18 queries already worked on the released community extension; this adds the missing 2.
Stacked on: #113 (edge-to-cloud quickstart + SRID/geodetic fix). Merge #113 first; GitHub will rebase this PR onto
