feat(runtime): host service-scoped KV capability

Browse Source 
Introduce an injectable, deadline-aware KvBackend boundary and link only the exact wasmeld:kv/store@0.1.0 import requested by a Component.

Namespace entries by service ID so revisions share state while services remain isolated, reject registrations without a backend, and enforce 256-byte keys and 64 KiB values.

Cover capability discovery, cross-revision sharing, service isolation, missing backends, and resource limits with Component integration tests.
