Law-N SQL API (law-n-sql-api)

Minimal HTTP API for Law-N:

• Accepts network.routes rows over HTTP
• Stores them in an in-memory table
• Exposes simple endpoints to:
  • list current rows
  • load/replace rows
  • run an N-SQL query over network.routes (if law-n-sql-core is available)

This is the first Law-N microservice: a small but real step toward CLSI (Cloud Layer Signal Interface).
