Add Court Rules integration page - #626

Summary

Adds an integration page for Court Rules, a free reference for U.S. federal and state court rules, local rules and judge standing orders. The Court Rules maintainers are submitting it.

The page documents court-rules-haystack (repo, MIT):

• CourtRulesRetriever returns court filing rules as Documents. The metadata carries the court, judge, rule type, citation and official source URL.
• CourtRulesToolset gives an Agent five read-only tools: list_courts, list_judges, get_judge_rules, search_filing_rules and list_court_holidays.

Why

Filing rules differ by court and by judge: page limits, courtesy copies, pre-motion letters, e-filing and service. Court Rules extracts them from the courts' published documents and serves them through a REST API, each with a citation and the source URL. This package makes that data available in Haystack pipelines and agents. The page shows a RAG pipeline and a filing-prep agent that combines the toolset with a firm's own checklists (BM25 over an InMemoryDocumentStore).

Validation

• Package tests: 75 passed on haystack-ai 3.0.0 and 3.2.0 (Python 3.12). CI passes on Python 3.10 to 3.13 with ruff, mypy and pytest: https://github.com/foklepoint/court-rules-haystack/actions
• The tests use httpx.MockTransport. No API key was used and no live API call was made.
• The RAG and agent snippets on the page are the files in examples/. They were run end to end with a scripted MockChatGenerator and stubbed Court Rules responses, not with a hosted model or the live API. Using the live API needs a free key from https://console.courtrules.app.
• The pip install command on the page was run against the published v0.1.0 tag.

Notes

• The package is not on PyPI yet. The page installs from a pinned GitHub tag, and the front matter has repo and no pypi.
• The change adds integrations/court-rules.md and logos/court-rules.png (400x400, the Court Rules logo). No other file changes.
• The type is Tool Integration. It can be changed if another type fits better.
• Prepared by an AI coding agent on behalf of the Court Rules maintainers.
