Module logger 

Stderr logger gated by a single config boolean.

When logging is true (the default), records from our crates at level debug and above (debug/warn/error) are written to stderr. When false, nothing is emitted. Output is restricted to our crates so third-party libraries don’t pollute the terminal.

RUST_LOG is still honored when set — useful for ad-hoc debugging — and is parsed as an env_logger-style spec with the configured baseline as the fallback default.
