## Did you read the Contributor Guide? - Yes, I have read the [Contributor Rules](https://sedona.apache.org/latest/community/rule/) and [Contributor Development Guide](https://sedona.apache.org/latest/community/develop/). ## Is this PR related to a ticket? - Yes, and the PR name follows the format `[GH-XXX] my subject`. Closes #3200. ## What changes were proposed in this PR? - Write the required zero coordinate count when serializing an empty `SinglePolylineGeography`. - Produce valid `LINESTRING EMPTY` WKB instead of a header-only, malformed byte sequence. - Allow `WKBGeography.fromS2Geography()` to round-trip an empty LineString through JTS while preserving its SRID. The malformed WKB was discovered while reviewing #3195. This PR isolates the pre-existing serialization defect from the `ST_MakeLine` feature. It does not define the separate behavior for `ST_MakeLine(EMPTY, non-empty)`, which is tracked by #3202. ## How was this patch tested? - Full common module suite: 1,181 tests, 0 failures. - Added an exact-WKB assertion for `010200000000000000`. - Added WKB-to-S2 and S2-to-WKB-to-JTS empty LineString round-trip coverage. - Formatting and commit hooks passed. ## Did this PR include necessary documentation updates? - No. This corrects malformed internal serialization without changing the public API. -- This is an automated message from the Apache Git Service.
