lucianschw-dev wires Mike into EU law

A standalone EU-law lookup module that pulls directly from EUR-Lex, the EU's official legal database.

The headline addition is a dedicated EU-law retrieval layer that talks to EUR-Lex - the European Union's canonical repository of legislation, case law, and treaties. The first cut shipped with six tools, including free-text search across legislation, case law, and treaties, plus targeted lookups by official identifier and a citation-verification helper.

Then came the honest revision. lucianschw-dev concluded the underlying structured-query endpoint was too unreliable in practice and stripped the three search tools out entirely, leaving a leaner module that fetches documents when you already know the official identifier and verifies citations offline. It's been smoke-tested against Schrems II. The trade-off is real: without search, callers need to arrive with an identifier in hand, so a free-text front door would have to come from elsewhere.

So what Anyone building EU-facing legal AI should watch this fork - it's a candid look at what actually works against EUR-Lex versus what only works in a demo.
