MCP tools served through a session bridge can now be refused as 'not yet presentable' instead of silently falling through
When Claude Code routes a call to an MCP tool (a tool provided by an external MCP server) served through a session bridge, it now checks a per-session record of that tool's state. If the tool is registered but its provider reports it isn't ready to be shown yet, the call now returns a not_served error directly, rather than falling through to try local or remote dispatch as it did before.
This should prevent Claude Code from attempting to use a bridge-served tool before it's actually ready, giving a clearer error instead of an unpredictable fallback attempt.
