Function configured_server_matches 

fn configured_server_matches(
    haystack: &str,
    server: &ConfiguredMcpServer,
) -> bool

True when haystack (a whitespace-normalized process cmdline) contains every match token of server. Leading npx/npm passthrough flags (e.g. -y) are dropped first: npx -y <pkg> re-execs into npm exec <pkg> with the flag stripped, so the tokens are the package spec (the first non-flag arg) plus everything after it - where the real distinguisher --cdp-endpoint <url> lives and survives into the process cmdline. Empty / all-flag args fall back to the bare command. Substring containment tolerates the process-side @version suffix.
