This PR addresses the request to improve overall clean code practices while perfectly aligning the README documentation with existing codebase capabilities.

Changes include:

  • Adding the missing .createDatabase(true) to the programmatic use case example in README.md, perfectly aligning it with what's documented in the dlock-jdbc sub-module and the required initial setup to avoid database errors.
  • Refactoring SimpleKeyLock.tryLock to adopt standard Java conventions by using .isBlank() instead of .trim().isEmpty().

Tests pass completely with no regressions.


PR created automatically by Jules for task 18385575067657375025 started by @pmalirz

- Added `.createDatabase(true)` to `JDBCKeyLockBuilder` in the main README's
  "Programmatic Usage" example to ensure accurate setup instructions aligned
  with sub-module documentation.
- Refactored `SimpleKeyLock.java` to use `String.isBlank()` instead of
  `trim().isEmpty()` for cleaner, standard string validation in Java.
