- Swapped legacy `zodToWireSchema` for `toolWireSchema` to normalize tool schemas.
- Updated `getSchemaPropertyKeys` in `tool-index.ts` to process schemas via `toolWireSchema`.
- Refactored tool token estimation in `context-usage.ts` to utilize the new schema helper.
- Fixed ArkType assertion checks in test helpers to correctly verify instances against `arkType.errors`.
- Aligned test suites and mock specifications with raw schema-based parameters instead of manually stringified JSON structures.
