migrate-waniwani-sdk-0.15-to-0.16
Migrate @waniwani/sdk 0.15 → 0.16
A self-contained migration for the single hop from 0.15.x to 0.16.0. Apply it when a project on 0.15 is moving to 0.16. It covers only that jump; for other version boundaries use the matching migrate-waniwani-sdk-<from>-to-<to> skill, or the general procedure in the SDK's changelog.
Precondition: the project is on @waniwani/sdk@0.15.x. If it is on an older version, migrate up to 0.15 first (that jump ships its own migration); if it is already on 0.16+, there is nothing to do here.
What 0.16 changes
Tracking becomes one typed track client on four surfaces (server waniwani(), the scoped client in tool handlers and flow nodes, useWaniwani() in MCP-app widgets, and chat.track on chat host pages), each attaching session identity automatically. Five breaking changes result, all mechanical.
