H3INDEXSET is a Set<H3INDEX> blob built from a static geometry at a given H3 resolution. Two new UDFs: - geoToH3IndexSet(GEOMETRY, INTEGER) returns H3INDEXSET — covers POINT, LINESTRING, POLYGON, MULTI*, and GeomCollection input. Caller passes geometry in EPSG:4326 (e.g. ST_Transform). - everIntersectsH3IndexSet_Th3Index(H3INDEXSET, TH3INDEX) returns BOOLEAN — true when the trajectory ever passes through any cell of the static set. These accelerate the trip x static cross-join queries (BerlinMOD Q4, Q7, Q11, Q12, Q15, Q17 on the bench). Q7-style intersection on BerlinMOD sf 0.005: 0.517 s without prefilter, 0.076 s with the prefilter (6.8x).

Bump the vcpkg meos pin dfdd2554 -> bb659c693 (MobilityDB accumulate/parity-1.4, PR MobilityDB#22) so the extension links the h3indexset static-geometry API (geo_to_h3index_set, ever_eq_anyof_h3indexset_th3index) and the extended-type C API (tcbuffer_from_mfjson, ...) — the universal unblock for the th3 prefilter UDFs (MobilityDB#131) and the extended-type ports. Adapt the binding to the bb659c693 API: - geo_as_ewkb(gs, endian, &n) -> geo_as_wkb(gs, WKB_EXTENDED, &n) (the WKB/EWKB consolidation to a variant parameter). - temptype_supports_linear -> temptype_continuous. - mult_* -> mul_* (temporal multiplication naming normalization). Reconcile 3 expected outputs to bb659c693's verified reference behaviour: - span -|- adjacency is now set-theoretic share-a-boundary (closed spans meeting at a boundary are adjacent): 1.0 -|- floatspan[1,3] (both directions) and the tint/tstzspan boundary case -> true (matches MobilityDB's own 005 test). - ln/log10/exp lifts no longer insert an interior turning point; results keep the input instant count (matches MobilityDB's 026 test). Build + full sqllogictest green (1727 assertions, 76 cases).

Register the H3INDEXSET type plus geoToH3IndexSet and everIntersectsH3IndexSet_Th3Index, backed by the MEOS geo_to_h3index_set / ever_eq_anyof_h3indexset_th3index API now available after the MEOS pin bump. These are the static-geometry H3 prefilter UDFs the portable BerlinMOD th3 queries (q02/q04/q05/q06/q10/q16) rely on. They register via the existing H3IndexTypes::Register* calls (no new wiring). Build + full suite green (1727). Folds open PR MobilityDB#131 (now unblocked by the MEOS pin bump).

Summary
Adds the two MobilityDuck UDFs that complete the h3 prefilter surface for trip × static-geometry cross-join queries (BerlinMOD Q4, Q7, Q11, Q12, Q15, Q17):
`H3INDEXSET` is a new logical type (alias on `BLOB`), storing a serialized MEOS `Set`.
Stacks on PR #129 (the th3index core).
Validation
BerlinMOD scalefactor 0.005 on a single-node DuckDB build, Q7-style intersection (every trip × every QueryPoint):
