GraalVM Recommendations

• G1GC: Use the G1 GC ('--gc=G1') for improved latency and throughput.
• PGO: Use Profile-Guided Optimizations ('--pgo') for improved throughput.
• AWT: Use the tracing agent to collect metadata for AWT.
• HEAP: Set max heap for improved and more predictable memory usage.
• CPU: Enable more CPU features with '-march=native' for improved performance.

Versioning

Add axion-release-plugin for versioning and releasing.
