Correct the scope-selection migration note and a stale test docstring
...
The migration entry named the wrong v1 trigger for the removed
authorization-server fallback: it fired when the protected resource
metadata was absent or omitted scopes_supported, not when it published an
empty list. Also note that the offline_access append needs a base scope,
so flows that previously drew only on the authorization server's list
no longer request it.

Align scope selection with the spec chain and stop mutating caller metadata
...
Drop the authorization-server scopes_supported tier from scope selection.
That list is the server's catalog rather than what the resource needs,
so falling back to it could request every scope the server supports
when the protected resource metadata published an empty list. The
chain is now WWW-Authenticate scope, then PRM scopes_supported, then the
caller-configured scope, then omit; an empty published list falls
through instead of pinning an empty scope. AS metadata is still consulted
for whether offline_access may be added.
The provider now works on a copy of the caller's OAuthClientMetadata, so
the flow's scope selection no longer rewrites the caller's model and the
configured-scope snapshot cannot pick up another provider's discovered
scopes when metadata is reused across providers.

Fall back to the caller-configured scope when the server advertises none
...
The OAuth client's scope-selection step overwrote the scope a caller
set on the provider on every 401, and when the server advertised no
scopes at all it left the token request with no scope. The configured
scope is now the last-resort tier after the WWW-Authenticate challenge
and the server's scopes_supported, matching the TypeScript SDK.
A source that yields no scopes (absent, null, or an empty list) now
falls through to the next tier instead of pinning an empty scope.

fix: reject trailing newline in tool-name and URI-template varname validation ( #3076 )
...
Python's $ with re.match also matches just before a single trailing newline, so tool-name validation accepted "name\n" and UriTemplate.parse accepted varnames like "foo\n". Switch both checks to re.fullmatch.
