Module client 

Registry client.

The Client resolves plugin metadata from the static-site catalog. Network access is abstracted behind the Fetcher trait so:

• production builds can plug in reqwest/ureq (or read from a mirrored checkout), and
• tests inject a MemoryFetcher holding the TOML documents verbatim, with no network.

The client only reads structured TOML; the actual artifact download (the [artifact] URL in a manifest) is handled by [crate::install].
