group-law layer: complete twisted Edwards addition law proven
Extraction widened to backend::serial::curve_models + edwards (own gen/,
209 defs). Adapted the reference Ed* proof suite: namespace rename +
Curve25519TraitsIdentity -> Curve25519_dalekTraitsIdentity. New opaque
externals (scalar_mul backends, get_selected_backend, decompress, sum,
from_slice) are axioms outside both certificate cones — verified by the
Phase-3 audit. All 21 proofs compile; field certificates unchanged.
Not claimed (matching the reference solution's honest scope): edAdd
associativity, scalar multiplication, decompress/compress, AVX2 backend.
