v0.50.3

[0.50.3 - 2026-01-14]

Fixed

• GFQL / let-ref: Documented and tested existing letrec semantics for ref; list bindings now accept implicit Chains.
• GFQL / schema: Apply call() schema effects during validation so enrichments like get_degrees are recognized by downstream filters, and prioritize boundary-call validation before schema errors.
• GFQL / filters: Treat boolean literal filters on object-typed columns as booleans instead of numeric mismatches.

Tests

• Tests / GFQL: Fixed cuDF compatibility in test files by using to_set() helper instead of .tolist() (cuDF doesn't support tolist())

Docs

• Docs / GFQL: Updated the GFQL remote notebook examples to use valid ref/edge traversals.
