Update at 2026-02-02-07-24 (#70)

This pull request updates the GitHub Actions workflows for building the
project with Gradle. The main improvement is ensuring that the `gradlew`
script has executable permissions before running it, which increases
reliability in CI environments.

**Workflow reliability improvements:**

* Added a `chmod +x ./gradlew` step before executing Gradle commands in
`.github/workflows/gradle.yml` to ensure the wrapper script is
executable.
* Added a `chmod +x ./gradlew` step before executing Gradle commands in
`.github/workflows/jars.yml` to prevent permission issues during the
build process.
