QElectroTech 0.100.1 is now installed locally, so the qet/ folder
gets its actual project file: five pre-named folios matching the
documented plan (synoptic, 48V DC, 230V AC, rooftop PV including the
sliding deck, monitoring/interlocks) with house title-block fields.
README updated from install instructions to open instructions.
Split the schematic tooling by audience: QElectroTech (IEC 60617,
versionable XML) for the 48V/230V/PV installation folios that
electricians and inspectors read, KiCad kept for in-house boards
(monitoring, solar-deck interlock). Seed qet/ with the folio plan
and conventions; record the decision.
