This pull request updates the GitHub Actions workflows for Maven and JNI builds, mainly to improve CI efficiency and reliability. The most significant changes involve enabling workflow runs on pull requests, optimizing Maven usage, and making the build process more robust.

Workflow trigger improvements:

• The Maven deploy snapshot workflow now runs on pull requests targeting the main branch, in addition to pushes to main and release/** branches.

Maven and build process enhancements:

• The Maven JNI workflow now enables the Maven dependency cache for faster builds and adds the -U -B flags to the mvn compile step for more reliable and non-interactive builds.
