giles ded7170540 identity: token exchange — downscope into an independent token (RFC 8693, +8 tests) ...

oauth.sx gains token_exchange(SubjectToken, RequestedScope): a valid access
token is downscoped into a NEW independent grant for the same subject
(subset only, else invalid_scope; inactive subject token → invalid_grant).
The exchanged token's lifecycle is independent of the subject token
(revoking either leaves the other active); exchanges chain. Least-privilege
handoff to downstream services. New tests/exchange.sx. 201/201.
