Fix verbose flag to use full runtime snapshots in JSON output

The verbose flag was accepted but never used - runtimeSnapshot was hardcoded to 'compact'.
Now when --verbose is passed with --output json, runtimeSnapshot is set to 'full' to include
full element details instead of the compact representation.

Updated tests to verify verbose mode produces full output as expected.
