v0.3.52

Fixes

• Benchmark timeout fix: waitForExit waited for status "exited" but GetContainerStatus only returns "running"/"stopped" — benchmark always timed out after 5 minutes. Now correctly detects when container stops.
• Benchmark permissions: Directory chowned to UID 999 (klever container user) to prevent "permission denied" on disk benchmark.
• Benchmark error reporting: On non-zero exit code, reads container logs and returns the actual error message (e.g., "permission denied") instead of a generic timeout.
