feat(bls): add CGO-optimized blst implementation with circl fallback

- bls.go: pure Go implementation using cloudflare/circl (!cgo)
- bls_cgo.go: CGO-optimized implementation using supranational/blst (cgo)
- types.go: shared constants and errors
- Simplified bls12381 build tags (cgo vs !cgo)
- Removed duplicate implementations (bls_new.go, internal.go)
- Fixed tests to work with both implementations
