Generate path-aware composition artifacts

Composition review

Estimate: 2 points.

What to build

Download already-resolved static compositions, generated typing, and slot addresses from the backend. Write coherent fallback indexes for ID/path/alias references across supported SDKs.

Implementation checklist

• Pass application/version/locale selection through artifact download and generation commands.
• Write the agreed manifests and ID/path/alias indexes, including dynamic-route discovery.
• Remove obsolete generated entries when regenerating or dropping aliases.
• Add unit tests for manifest/index generation and file/command integration tests where available, using provider contract fixtures.
