Author youaskm3 app manifest and WASM component manifests

[enricopiovesan]

Summary

Create the app manifest (manifests/youaskm3/app.manifest.json) and WASM component manifests (manifests/youaskm3/components/) that define the youaskm3 app bundle for Traverse validation and registration.

Why

Specs 044 and 046 require a downstream app to provide an app manifest and concrete WASM component manifests before Traverse can validate and register the app. These manifests are the source of truth for what capabilities and workflows the runtime loads.

Definition of Done

• manifests/youaskm3/app.manifest.json exists and is schema-valid per spec 044
• At least one WASM component manifest exists in manifests/youaskm3/components/
• All referenced WASM binaries exist or are documented as external build outputs
• traverse-cli app validate --manifest manifests/youaskm3/app.manifest.json --json exits 0
• No placeholder or all-zero WASM digests

Governing specs

• 044-application-bundle-manifest (approved)
• 046-public-cli-app-registration (approved)

Depends on

#10 (youaskm3 plan), #9 (runtime pinned)
