docs: fix v0.1.46 changelog entry to match actual method names

The changelog entry for #620 listed add_mcp_server()/remove_mcp_server(),
but the commit actually added reconnect_mcp_server()/toggle_mcp_server()/
stop_task() and the McpStatusResponse type. The commit's own CHANGELOG
block had the correct names; this was a transcription error.
