v0.1.0.dev0 - pre-alpha snapshot (first archived for DOI)

First Zenodo-archived snapshot of GROUPOID, created to provide a citable DOI.

Status: pre-alpha research prototype. See STATUS.md and LIMITATIONS.md for exactly what is implemented and tested versus not. This is not a working federated-learning framework; it is a small, honestly-scoped library of groupoid / Riemannian-geometry primitives (Karcher mean, morphism composition, H^1 holonomy, sheaf Laplacian, aggregation pipeline).

Known issues tracked openly: #8 (sheaf Laplacian off-diagonal block), #9 (compute_h1 missing-edge handling), #10 (persistence per-dimension labels).
