             Summary: Add GEOGRAPHY logical type model
                 Key: FLINK-39904
                 URL: https://issues.apache.org/jira/browse/FLINK-39904

Problem
Flink has no native logical type for geography values.

Goal
Introduce GEOGRAPHY into the core Flink type system.

Solution / Scope
Add LogicalTypeRoot.GEOGRAPHY and GeographyType with expected equality, nullability, summary, and serializable string behavior.

Acceptance Criteria
GEOGRAPHY and GEOGRAPHY NOT NULL are represented correctly as LogicalType instances.
