Module endpoint 

Canonical URL parser for the SDK’s connection string.

The contract (from every phase6_sdk-*-rpc/proposal.md):

• vectorizer://host:port → RPC on the given port.
• vectorizer://host (no port) → RPC on default port 15503.
• host:port (no scheme) → RPC.
• http://host:port / https://host:port → REST (legacy fallback).
• Anything else → ParseError::UnsupportedScheme.

URLs that carry credentials in the userinfo (user:pass@host) are REJECTED — credentials cross the wire in the HELLO handshake, NOT in the URL. This avoids accidentally logging or shell-history-saving a token-bearing URL.
