incutec-OpenESC_20X20/hardware/4in1-mini.kicad_pro
JustStan d1614eee5c Fix contradictions and duplicated information 
Contradictions, resolved against the design files:
- GitHub repo description corrected to KiCad 10 and 6S (schematic/PCB carry
  generator_version 10.0; DOC_INPUT is "+BATT 6S", no 3S floor is documented).
- DOC_NAME text variable now "OpenESC-20x20", matching the repo rename, so the
  old slug stops leaking into title blocks and fabrication exports.
- 20x20-ESC-QC/README.md no longer claims project-local libraries only: 44 of
  the 45 fixture footprints come from KiCad's stock TestPoint library. Also
  records that the fixture schematic is a stub, so the one ESC-QC symbol is
  unused.
- esc_thermal.py header and 20x20 profile name state that SP40N03GNJ is a
  superseded power stage and its numbers do not describe the shipping board
  (24x DOY180N03T). Parameters left untouched, re-parameterization needs the
  DOY180N03T datasheet.
- *.kicad_dru removed from .gitignore: hardware/4in1-mini.kicad_dru is a
  hand-authored DRC rule, a design input, not generated output.
- The "3D exports" ignore rule was malformed (**/.step matched nothing). Now
  hardware/*.step and 20x20-ESC-QC/*.step, which leaves the *.3dshapes/
  library assets tracked.

Duplication, each fact kept in one place:
- README specification table dropped, the full table lives in DESIGN.md.
- Production-export and flash-script statements kept in README Manufacturing;
  the layout rows and DESIGN.md now link there.
- licensing/README.md removed, its one unique sentence moved into the README
  license section. THIRD_PARTY.md and TRADEMARKS.md keep the real content.

Removed:
- hardware/datasheets/COMPONENT_REVIEW.md, a v0.3 audit describing a power
  stage, current sense and regulator that are not in the design files.
- hardware/scripts/v_beta_hygiene_fix.py, an applied migration whose target
  file and all three source strings no longer exist, and which byte-edits
  .kicad_sch against CONTRIBUTING.
- hardware/4in1-mini.step (18.3 MB) and 20x20-ESC-QC/QC-20x20-PCB.step,
  regenerable board exports now correctly gitignored.
- 20x20-ESC-QC/ESC-QC.pretty/.gitkeep, the directory holds a real footprint.
