fix(command-palette): match file results against the full relative path

Cmd+P scored server file hits by basename only, so a query like
"solo-is-a" returned nothing for solo-is-a-team-size/index.md.
Score by relativePath and widen the server candidate limit to 40
so client-side reranking has enough to work with.
