Doxygen XML

The Infrintia docs include Doxygen configuration so low-level API references can be generated alongside Sphinx output when Doxygen is available.

Generate XML from the documentation repo root:

make doxygen

The product configuration writes generated files to docs/doxygen/build/infrintia/xml. Generated XML is ignored by git and can be rebuilt at any time.

The Infrintia source checkout was not found. Set INFRINTIA_SOURCE or place the repo at ../infrintia before generating XML.
