Discovery collapses differently-named MCP entries that point at the same
command/args/env/cwd (or url/headers) into one connection, keeping whichever
loaded first and dropping the rest as aliases. requestIdFormat changes the bytes
sent on the wire, same as auth/oauth which the comparator already covers, so a
higher-priority alias lacking the field could shadow a lower-priority entry that
set it, silently falling back to string ids for a server that needs numbers.
Add requestIdFormat to isSameMCPConnection, normalized against its own default so
an explicit "string" is not treated as a different connection than leaving it
unset. timeout stays excluded, since it is a client-side knob that never touches
the wire.
