This implementation heavily depends on there being a lockfile, meaning JSR specifiers will always diagnose as uncached unless it's there. In practice this affects cases where a `deno.json` isn't being used. Our NPM specifier support isn't subject to this. The reason for this is that the version constraint solving code is currently buried in `deno_graph` and not usable from the LSP, so the only way to reuse that logic is the solved-version map in the lockfile's `packages.specifiers`.
