Module config 

Configuration file parsing and merged configuration for cqlsh-rs.

Handles ~/.cassandra/cqlshrc (INI format) parsing, environment variable loading, and merging with CLI arguments following the precedence rule: CLI > environment variables > cqlshrc > defaults.

Many fields are defined ahead of their use in later development phases.
