Footprint policy auditor for PCB libraries

[salitronic]

New feature: a tool that checks whether a footprint library is internally consistent.

Point it at a PcbLib and it works out what that library normally does (silkscreen layer, designator placement and height, whether parts carry a 3D model, pad numbering and drill rules) and lists the footprints that don't match. It doesn't enforce a fixed house style. It learns each library's own conventions and flags the outliers, so it works on any library.

It also repairs a lot of what it finds. It creates missing designators, moves them onto the right layer, sets them to the standard height, and centres them on the part. Anything it can't change safely is reported by name so you can fix it yourself.

It runs through the MCP tools, and there's a read-only Footprints tab in the web dashboard that shows the audit.
