v0.31.4 — named arguments and monotonicity metadata

Added

• Support for the current VGI 2 named-argument declaration model.
• Scalar-only per-argument monotonicity metadata, aligned to declaration order (including named arguments and a single variadic slot).
• Conservative UNKNOWN behavior when no claim is declared.

CI

• The release integration matrix now uses launcher, shared-memory, and HTTP lanes. Raw stdio remains available for local compatibility testing but is no longer a release gate.

The DuckDB 1.5 extension validates and preserves this protocol metadata; a future DuckDB 2 optimizer adapter can consume it.

What's Changed

• test: add executable Filter v2 conformance corpus by @rustyconover in #72
• Fix VGI 2.0 CI and TypeScript list generation by @rustyconover in #73
