DXF generation and validation

Provenance: maintained in earthtojake/text-to-cad. Use the installed local skill files as the runtime source of truth; the repository link is only for provenance and release review.

Setup

Run cadgen through uv, so this skill's commands share one installation, and its warm build daemon, with the CAD app's server:

• cadgen below means uvx --no-config --managed-python --python 3.13 --from cadgen==0.7.20 cadgen
• python below means uvx --no-config --managed-python --python 3.13 --from cadgen==0.7.20 python

The first run downloads that installation and the first snapshot its headless browser; later runs reuse both.
