v0.1.16

Added

• Opt-in zodVariantTable command, insert, update, public DTO, and tool boundaries with per-variant masks, native storage IDs, and strict discriminators.
• Repository-hosted cvx-kit agent skill, installable from GitHub through the skills CLI, with task-specific access to the full documentation.

Changed

• Keep documentation in skills/cvx-kit/references and ship only the README as npm documentation.
• Verify portable skill references in CI and before publication; remove obsolete planning and explainer artifacts.

Fixed

• Preserve optional/nullable refinements in derived tool inputs and reject bigint command literals before JSON Schema generation.
