feat(libstore): tie AWS CRT logging to Nix verbosity level

Browse source 
Map Nix's verbosity levels to AWS CRT log levels so users can
debug SSO authentication issues without modifying code:

- Default/warn: AWS Warn (errors/warnings only)
- Chatty (-vvv): AWS Info (credential provider actions)
- Debug (-vvvv): AWS Debug (detailed auth flow)
- Vomit (-vvvvv): AWS Trace (full CRT internal tracing)

This makes it easy to diagnose SSO issues with:
  nix copy -vvvv --to s3://bucket?profile=foo ...
