Default fastmcp.Client to mode="auto"; surface extensions=/result_claims=
...
Client negotiates the newest mutual protocol era by default (probe
server/discover, fall back to the initialize handshake). ProxyClient and the
inspect utility explicitly pin the handshake era so proxy forwarding and
server_info reads are unchanged. SSE and multi-server config transports are
legacy-only. extensions= and result_claims= (SEP-2133) are thin passthroughs
to the SDK session.

Repoint tests and examples off removed deprecations
...
Replaces FastMCP.as_proxy() helper calls with create_proxy(), rewrites the
mount() as_proxy=/prefix= kwarg tests to plain mount() (the params are gone),
and deletes deprecation-only tests for as_proxy() and remove_tool().

fix: TransformedTool sync fn crash and schema mutation ( #3823 )
...
* fix: TransformedTool sync fn crash, schema mutation, output_schema=False
- Handle sync transform_fn in run() using is_coroutine_function check
instead of unconditionally awaiting (fixes TypeError crash)
- Deep copy parent property schemas to prevent mutation corruption
- Accept output_schema=False via BeforeValidator (converts to None)
- Remove inaccurate docstring claiming str/None shorthand for transform_args
Fixes #3821
