Replace the C++ implementation with the Rust port
The Rust port (formerly gipfel-rs) is now the official successor to the
FLTK/GSL C++ code base. This squashes the port into a single commit and
removes the C++ sources (they remain in the git history below).
Layout:
crates/gipfel-core headless core: hills, panorama geometry, projections
(maxima-generated derivatives), pure-Rust LM fit,
gipfel: JPEG comment + EXIF I/O, profiles, stitching
crates/gipfel-cli command-line tools (export, info, stitch, profiles)
crates/gipfel-app Cosmic DE (libcosmic) GUI, binary name `gipfel`
codegen/ maxima scripts + regen.sh for the projection code
tests/ golden files + C++ reference harnesses (historical)
The original README is kept for now; it will be updated to describe the
Rust build. gipfel.dat, AUTHORS, ChangeLog and NEWS are unchanged.
