📝 Walkthrough

Walkthrough

This pull request adds Maven Wrapper support to the project by introducing wrapper scripts and configuration files, then replacing direct mvn invocations with ./mvnw across all CI/CD workflows for consistent Maven execution across platforms.

Changes

Cohort / File(s)	Summary
CI/CD Workflow Updates .github/workflows/build.yml, .github/workflows/publish-central.yml, .github/workflows/publish-github.yml	Replace direct mvn command invocations with ./mvnw wrapper script across build, publish-central, and publish-github workflows. Preserves all Maven goals, flags, and environment variables; only changes the executable entry point.
Maven Wrapper Configuration .mvn/wrapper/maven-wrapper.properties	New configuration file specifying wrapper version 3.3.4, distribution type (only-script), Maven 3.9.12 distribution URL, and SHA-256 checksum for integrity validation.
Maven Wrapper Scripts mvnw, mvnw.cmd	New shell and Windows batch wrapper scripts that bootstrap and execute Maven. Handle environment setup, Java resolution, distribution download from configured URL with optional authentication and checksum verification, caching under user's Maven directory, and platform-specific unpacking and execution logic.

Poem

🐰 A wrapper so fine, from the Maven's great store,
With scripts that bootstrap, and download with flair,
No more chasing mvn through the sys-path's maze,
Just ./mvnw hops swiftly, cross-platform with care,
SHA-256 whiskers twitching, checking each byte!
