Koichi ITO 33525d6494 Release 1.5.0
This release makes the client answer a server's `ping` with the empty result the specification requires:
earlier clients replied with Method not found over Streamable HTTP and stayed silent over stdio,
so a server that checks liveness dropped their long-lived sessions. On the OAuth side,
the embedding application can refuse an authorization request through `authorization_request_validator`,
and stored tokens are refreshed only against the authorization server that issued them.

The validator is what makes this a minor release. The refresh check is the one behavior change:
when the authorization server named for a session differs from the one that issued the stored tokens,
the client reauthorizes instead of refreshing, and tokens stored by earlier releases, which carry no issuer,
keep refreshing.
