Rename the core package to periscopex, update UI/docs/Docker/deploy defaults to periscope.michelebigi.it, and keep legacy version/storage key aliases so existing projects keep working. Co-authored-by: Cursor <cursoragent@cursor.com>

"""Errata catalog — workaround on the graph, no scraping.
|
|
|
|
Favor: known MPN with a pull-up workaround missing on the net → PE-ERRATA-001.
|
|
Against: MPN not in catalog is silent (even TI-looking); workaround pull-up
|
|
present is silent; catalog entry without url is skipped.
