feat: production MCP server with Israeli legislation (multi-source)

Complete production implementation with shell+adapter architecture,
13 MCP tools, SQLite FTS5 search, and multi-source ingestion pipeline.

Ingestion fetches from UCI mirror, UNODC SHERLOC PDFs, and Knesset
mobile PDFs (135 provisions, 33 definitions). 3 acts with full text,
7 acts metadata-only due to gov.il/nevo.co.il access restrictions.
Knesset OData API used for metadata enrichment.
