:content
Returns runtime metadata for a UCE compilation unit.

The returned tree is supplied by the host runtime and may include normalized source/artifact paths, compile/runtime status, ABI/wasm availability, timing counters, mtimes, and exported API declarations. Treat absent fields as unavailable rather than as false.

If `path` is relative, it is resolved by the same host unit resolver used for unit calls/components.

Because unit metadata lives in worker process memory, request and timing counters reflect the current runtime process, not an aggregate across every worker process.
