Add Clarvia AEO Score badge (60/100) to README

[digitamaz]

Hi! 👋

I wanted to let you know that parliament.uk:search has been reviewed on Clarvia and scored 60/100 for agent-readiness (MCP compatibility, structured output, documentation quality, etc.).

You can add the badge to your README with this one-liner:

[![Clarvia AEO Score](https://clarvia.art/api/badge/scn_366133d06c82.svg)](https://clarvia.art/tool/scn_366133d06c82)

It dynamically updates as your score improves. Feel free to close if you're not interested — no hard feelings!
