- Rename KiCad project/schematic/board (and local .prl) to drop the '+',
updating all internal cross-references (project name, sheetfile, title blocks)
- Remove the '+' from Gerber/drill/job filenames and the job file's internal
Name/Path references; rebuild the upload zip with clean names
- Stop tracking gerber/ (derived artifacts): untrack, gitignore, and publish
the fabrication zip as a GitHub Release asset instead
- README/CHANGELOG: point fabrication data at the release, mark the '+' naming
issue as fixed, refresh the repository layout
