Subject: [PATCH 05/19] fix: scan all JSON lines in extract_run_id to handle
 Java workload output

The previous implementation hardcoded line index 1, which failed for the
Java workload where APX may emit the run_id JSON on a different line or
where _combine_command_output inserts [stderr] content between lines.

Now scans all JSON-looking lines (same pattern as _extract_session_id),
returning the first one that contains a valid run_id.

Subject: [PATCH 06/19] fix: revert APX Java cmd to base64 approach, remove
 file copy steps

The cp /tmp/CpuBurnerOriginal.java approach failed because the file is
not present on the remote target at workload execution time - it was only
copied to the runner host, not the SSH target. The original base64 inline
approach is self-contained and does not depend on any pre-staged files.

Also removes the now-unnecessary workflow steps that copied the Java file
to the runner and /tmp.
