[DX-4553] Optimize Integration Tests Workflow

[kalverra]

Integration Tests Parallelization & Runner Optimization

• Expanded AI skill to cover right-sizing runners and conduct overall structural change trials
• Run go test code compilation and build together
• Pass a pre-built binary to the Docker container instead of rebuilding it
• Some caching and build optimizations for Integration Tests

Runner & Structure Changes

Approach	Runner	Structure	Stability	Runtime	Runtime Delta (Abs/%)	Cost	Cost Delta (Abs/%)
Old	cpu=16/ram=64/family=m7i+m8i/spot=co	Sequential GreaterThanFinalityTests (13:12), Go compile inside Docker (5:22)	Pass	22:01	+0:00 (+0%)	$0.2100	+$0.00 (+0%)
New	cpu=32/ram=64/family=c7i-flex/spot=co	Parallel matrix split (OnSource/OnDest), host prebuilt Docker binary	Pass	16:45	-5:16 (-23.9%)	$0.1850	-$0.0250 (-11.9%)
