Replaces the GEOS round-trip in ST_Boundary with direct geo-traits traversal and incremental WKB output. Preserves GeometryCollection aggregation, dimensionality, empty outputs, and the mod-2 boundary node rule for MultiLineStrings. Local Criterion samples improved Polygon(10) from ~49.3 ms to ~13.5 ms and Polygon(500) from ~803 ms to ~662 ms. Verified with cargo test -p sedona-geos (275 tests) and clippy with warnings denied.\n\nCloses #303
