mrwulf 8440b53bdc Add scalar-layer foundation (Scalar52 arithmetic mod ℓ) ... Transpile the Scalar52 limb backend (backend::serial::u64::scalar add/sub/mul/square/montgomery_*) from Rust to Lean via Charon/Aeneas, scoped at the function level to the iterator-free arithmetic core. - verification/extract-scalar.sh: function-level Charon/Aeneas extraction - verification/gen/CurveScalar/{Types,Funs}.lean: transpiled model (28 defs) - verification/gen/CurveScalar/{TypesExternal,FunsExternal}.lean: hand-written external models (subtle.Choice + 2 subtle fns; namespace = curve25519) - verification/Proofs/ScalarDenote.lean: semantic foundation — Scalar52 denotation into ℤ/ℓℤ, limb-bound invariant, and L_val (the transpiled constants::L denotes exactly the group order ℓ, kernel-checked) - verification/check-scalar.sh: guarded compile of the four gen modules plus the denotation foundation check-scalar.sh passes: gen compiles; denotation + L = ℓ proven. add/sub/mul remain in progress.
