release/: JLCPCB order files when the repository makes them

A repository with .gitea/scripts/jlcpcb-files.py (harNES) gets
<board>-<tag>-jlcpcb-bom.csv and -jlcpcb-cpl.csv (rotations corrected per
LCSC part) in release/: the script runs with --force on a copy of hardware/
without the committed jlcpcb/ folders, so nothing stale is taken. When it
refuses a board (DRC, missing correction), release/README.md and a workflow
warning say why; the generic -cpl.csv then is the only placement file.
