Adds docs/colabfold-macos-install.md, a reproducible recipe for
installing LocalColabFold (ColabFold + AlphaFold2 weights) on Apple
Silicon Macs, so users can predict protein structures locally and feed
the resulting PDBs / confidence scores into a graphify corpus.
Notes upstream LocalColabFold's current top-level installer hardcodes
Linux x86_64 Miniforge and jax[cuda12], which fail on Apple Silicon (no
macOS CUDA wheels, no NVIDIA GPU). Recommends the bundled v1.5.5 M1
installer as the working Apple Silicon path. ColabFold 1.6.1 with
JAX 0.4.23 CPU build, verified by 60s smoke test on a 62-residue FASTA.
Linked from README.md under the existing 'Optional integrations' section
(also added by this PR if not already present from #620).
