Spell 2.0 Migration

Spell 2.0 groups secondary APIs, removes aliases, makes asynchronous checks explicit, and requires declarative definitions for JSON Schema export.

Update secondary API imports

Move secondary operations to their 2.0 grouped entry points. Replace removed aliases with the canonical API name before upgrading.

Make asynchronous checks explicit

Audit validation flows that may perform asynchronous work. Use the explicit 2.0 asynchronous check contract rather than relying on synchronous parsing paths.

Define schemas declaratively for JSON Schema

JSON Schema export now requires a declarative schema definition. Update generated-schema integrations to provide that definition instead of inferring it from unsupported schema forms.

Review the Usage Guide and API Reference for current schema, parser, diagnostics, and JSON Schema contracts.
