docs(readme): remove uiServer.metrics migration notes

Drop the `#### Migration notes` block under the worker process model
section that documented the `uiServer.metrics.enabled=true` listener-
inheritance change. Operational guidance lives with the feature
documentation; this stand-alone block was redundant.

-- `uiServer.metrics.enabled=true` now exposes `/metrics` on the listener of the configured `uiServer.type` (`http`, `ws` or `mcp`), inheriting that listener's `accessPolicy` and `authentication`. Operators previously relying on the silent disable when `type='ws'` or `type='mcp'` must set `metrics.enabled=false` (or remove the block) if they do not want the endpoint, and verify firewall posture on the UI server port. `HEAD /metrics` (e.g. `curl -I`) returns identical headers to `GET`, including `Content-Length` measured in UTF-8 bytes of the GET body.
