Generalizes camera modeling from a single pixel-scale/viewing-angle pair
to a full pinhole camera (3D orientation + position + intrinsics),
projected via true perspective (not just uniform cosine compression),
plus 2D beam pointing and per-plane z uncertainty. Every nominal
geometry value is now paired with an explicit tolerance that determines
whether it's held fixed or refined jointly with the mode fit.

Full implementation of Laguerre-Gauss modal reconstruction for gyrotron
beam diagnostics, per the approved design spec, plus tests, docs, and
a runnable end-to-end example.
