Fix .silol.series generation

[wilfonba]

This PR moves the generation of the .silo.series file before the failure message in MFC.sh. If post process failed, then the silo series file wouldn't be generated. I'm not sure how this got reordered, because I thought I'd done the correct ordering when I first merged this. Git blame shows that I just did it wrong though.

Copilot was unable to run its full agentic suite in this review.

This PR fixes the ordering of .silo.series generation so it happens before the post-process failure path in MFC.sh, ensuring the series file is still produced when post-processing fails.

Changes:

• Move the generate_silo_series.py invocation earlier in the post_process target block.
• Ensure .silo.series generation occurs before the $code == 22 early-exit error message.

Findings:

generate_silo_series.py now runs unconditionally even when post_process has failed

In run_epilogue, the diff moves the generate_silo_series.py invocation from after the error-exit checks to before them:

+% if target.name == 'post_process':
+    python3 "${MFC_ROOT_DIR}/toolchain/templates/include/generate_silo_series.py" '${os.path.dirname(input)}'
+% endif
+
     if [ $code -eq 22 ]; then
         ...
     fi

     if [ $code -ne 0 ]; then
         exit 1
     fi

-% if target.name == 'post_process':
-    python3 "${MFC_ROOT_DIR}/toolchain/templates/include/generate_silo_series.py" '${os.path.dirname(input)}'
-% endif

Because code=$? is captured from post_process before this block, the error-exit logic ($code -ne 0) still correctly terminates on failure. However, the silo-series script is now invoked before that check, so it will run even when post_process exited non-zero (including the case-file-error code 22). Previously it only ran on success.

Running generate_silo_series.py over incomplete or corrupt post-process output is likely to produce a broken silo series and may mask the real error by emitting spurious output before the failure message.
