Adopt Traverse platform reference clients from runtime repo

[enricopiovesan]

Outcome

Make this repository the canonical home for all checked-in application UI, platform client demos, and application-starter/reference source currently under the Traverse runtime repository's apps/ directory.

Scope

• Adopt the React, browser-consumer, Android, and macOS client/demo sources currently maintained under Traverse apps/.
• Adopt youaskm3-starter-kit and other application-starter/reference material as Reference Apps-owned artifacts.
• Separate reusable/reference source from runtime-only manifests, fixture agents, and conformance inputs.
• Preserve or replace each app's build, smoke, and public-contract validation.
• Make every adopted artifact consume released/public Traverse surfaces only; no private runtime imports or repository-relative coupling.
• Update user-facing documentation to point to the canonical Reference Apps paths.

Definition of done

• React, browser, Android, and macOS reference clients have canonical homes in reference-apps.
• Starter/reference source has a canonical home, owner, and supported validation command in reference-apps.
• Runtime-only fixture manifests and agents remain in Traverse under the examples/ destinations established by the ownership-boundary ticket.
• Each adopted application/starter has reproducible build or smoke validation in this repository.
• All adopted artifacts use only intended public Traverse contracts or SDKs.
• Documentation identifies this repository as the source of truth for applications and starter material.
• The corresponding Traverse source directories can be removed without losing supported demo or onboarding coverage.

Dependency

Blocked until Traverse #703 publishes the ownership inventory and fixture destinations. Coordinate the platform slices with existing Reference Apps #113–#116 and their SDK prerequisites; this ticket owns repository migration and source-of-truth acceptance, not SDK implementation.

Project state: Blocked on traverse-framework/traverse#703. That ticket records the ownership rule and path-by-path inventory; this migration starts only after it separates UI/client source from runtime fixtures.

[enricopiovesan]

Consolidated migration scope: this ticket now owns both platform-client and starter/reference-source migration. It coordinates with #113–#116 for platform implementation, while retaining its separate repository-ownership DoD.

Unblocked → Ready

Traverse #703 closed via PR #707 (and prior #705): ownership inventory recorded and runtime fixtures relocated under examples/.

This ticket is Ready for adopting Traverse apps/ UI/client/starter source into Reference Apps.

Released via PR #156. Adopted android-demo, browser-consumer, macos-demo, react-demo, youaskm3-starter-kit with offline smokes; live adapter smokes use TRAVERSE_REPO.
