📝 Walkthrough

Walkthrough

A GitHub Actions CI workflow is added to enforce code formatting via Spotless, a Maven plugin is configured to check and apply formatting rules across Java source files, and an unused import is removed to comply with the formatting standards.

Changes

Spotless Code Formatting Setup

Layer / File(s)	Summary
Plugin Configuration pom.xml	Spotless Maven plugin (v2.46.1) is configured to remove unused imports, trim trailing whitespace, and format annotations across src/main/java and src/test/java.
CI Integration .github/workflows/ci.yml	GitHub Actions workflow CI-pipeline runs on pushes to main and pull requests, executing Maven clean verify and spotless:check with Java 25 (Temurin) and Maven caching.
Code Cleanup src/test/java/.../LlmClientTest.java	Unused LlmUnavailableException import is removed to comply with Spotless enforcement rules.

🐰 Hoppy checks hop into the CI,
Spotless rules make code so spry,
Imports unused fade away,
Formatting shines in GitHub's day!
