fix(sdk): forward --ws workstream flag through query dispatch (#2546)

* fix(sdk): forward --ws workstream flag through query dispatch (closes #2524)

- cli.ts: pass args.ws as workstream to registry.dispatch()
- registry.ts: add workstream? param to dispatch(), thread to handler
- utils.ts: add optional workstream? to QueryHandler type signature
- helpers.ts: planningPaths() accepts workstream? and uses relPlanningPath()
- All ~26 query handlers updated to receive and pass workstream to planningPaths()
- Config/commit/intel handlers use _workstream (project-global, not scoped)
- Add failing-then-passing test: tests/bug-2524-sdk-query-ws-flag.test.cjs
