Paper E2E v1.2.0

This release focuses on runner reliability, environment validation improvements, and Gradle plugin enhancements.

Bug Fixes

• Runner stability: Added a server process check before sending the stop command, preventing errors when the process is already gone
• Environment validation: JAVA_PATH is now validated alongside SERVER_JAR and SERVER_DIR during startup checks, catching misconfigurations early
• Error output capture: Added a stderr handler to the server process so error output is now captured and logged instead of silently dropped
• Safe shutdown: Removed a redundant process.exit(1) call and corrected the exit code used in the safety-net shutdown path
• Bot version: The Mineflayer bot now reads the Minecraft version from MC_VERSION environment variable instead of the hardcoded '1.19.4'
• GuiItemLocator: Fixed internal calls to deprecated GuiWrapper methods

Features

• Plugin download support: Gradle plugin E2E tasks (TestE2ETask) can now download plugins as part of the task setup
• MC_VERSION env var: MC_VERSION is now passed through as an environment variable in TestE2ETask, enabling version-aware test runs

Refactoring

• Replaced waitAbit with pollForAbsence for error validation in the runner, making error-state detection more reliable and deterministic
• Renamed test file extensions for consistency across the project

Chore

• Added a version bump script and aligned project versioning
