Pull request overview

This PR introduces a new Java rule GCI99 to detect usage of common CSV libraries (via imports) and recommend using columnar formats like Parquet, and wires it into the plugin’s rule set, quality profile, and tests.

Changes:

• Added the GCI99 rule implementation (AvoidCSVFormat) and registered it in JavaCheckRegistrar.
• Added rule metadata documentation/resources (GCI99.json, GCI99.html) and enabled the rule in creedengo_way_profile.json.
• Added unit + integration test coverage for the new rule (JUnit CheckVerifier + GCIRulesIT + IT test-project sources).
