* fix(proxy): use return value from CustomLogger.async_post_call_success_hook
Previously the return value was ignored for CustomLogger callbacks,
preventing users from modifying responses. Now the return value is
captured and used to replace the response (if not None), consistent
with CustomGuardrail and streaming iterator hook behavior.
Fixes issue with custom_callbacks not being able to inject data into
LLM responses.
* fix(proxy): also fix async_post_call_streaming_hook to use return value
Previously the streaming hook only used return values that started with
"data: " (SSE format). Now any non-None return value is used, consistent
with async_post_call_success_hook and streaming iterator hook behavior.
Added tests for streaming hook transformation.

* fix(mcp): Add standard MCP URL pattern support for OAuth discovery (#17272)
OAuth discovery endpoints now support both URL patterns:
- Standard MCP pattern: /mcp/{server_name} (new)
- Legacy LiteLLM pattern: /{server_name}/mcp (backward compatible)
The standard pattern is required by MCP-compliant clients like
mcp-inspector and VSCode Copilot, which expect resource URLs
following the /mcp/{server_name} convention per RFC 9728.
Changes:
- Add _build_oauth_protected_resource_response() helper
- Add oauth_protected_resource_mcp_standard() endpoint
- Add oauth_authorization_server_mcp_standard() endpoint
- Keep legacy endpoints for backward compatibility
- Add tests for both URL patterns
Fixes#17272

* Test was relocated
* refactor(mcp): Extract helper methods from run_with_session to fix PLR0915
Split the large run_with_session method (55 statements) into smaller
helper methods to satisfy ruff's PLR0915 rule (max 50 statements):
- _create_transport_context(): Creates transport based on type
- _execute_session_operation(): Handles session lifecycle
Also changed cleanup exception handling from Exception to BaseException
to properly catch asyncio.CancelledError (which is a BaseException subclass
in Python 3.8+).

* test(mcp): Fix flaky test by mocking health_check_server
The test_mcp_server_manager_config_integration_with_database test was
making real network calls to fake URLs which caused timeouts and
CancelledError exceptions.
Fixed by mocking health_check_server to return a proper
LiteLLM_MCPServerTable object instead of making network calls.
* test(mcp): Fix skip condition to properly detect claude model names
The skip condition for missing API keys was checking for "anthropic" in
the model name, but the test uses "claude-haiku-4-5" which doesn't match.
Updated to check for both "anthropic" and "claude" model patterns.
Also added skip condition for OpenAI models when OPENAI_API_KEY is not set.
