The Banderwagon prime-order group used by Verkle / IPA had been vendored internally under lux/crypto/ipa/banderwagon. Extract it to lux/crypto/banderwagon as the canonical Lux public surface; rewrite all internal ipa callers (prover, verifier, config, multiproof, common, transcript, test_helper, tests) to import from the canonical home. - Provenance comment on every file: github.com/crate-crypto/go-ipa (Apache-2.0 / MIT dual). Adds LICENSE-GO-IPA-APACHE2 and LICENSE-GO-IPA-MIT alongside the package. - Element / Generator / Identity / Fr / MSMPrecomp / PrecompPoint / CompressedSize / UncompressedSize / SetBytes / SetBytesUncompressed / ElementsToBytes / BatchToBytesUncompressed / BatchNormalize / MapToScalarField / BatchMapToScalarField / Add / Sub / Double / Neg / ScalarMul / MultiExp now have one and only one home: lux/crypto/banderwagon. - Verkle (parallel branch) will switch its banderwagon import to this canonical surface. - KAT vectors from the upstream go-ipa Verkle reference suite preserved (TestEncodingFixedVectors, TestPointAtInfinityComponent) plus all precomp MSM-vs-gnark random-round tests (1000 * NumCPU rounds). Tests: go test ./banderwagon/... ./ipa/... — all PASS (banderwagon 27s, ipa 16s, ipa/bandersnatch 24s, fp/fr 4s+2s, common 3s).
