v0.1.5

Pure additive release. Re-exports the InkChallenge, InkRejection, InkResolution, InkTransport types and the InkTransportSchema constant from the package root. Adopters writing handshake-aware receivers can now type their state-machine without reaching into a deep path. No wire-level changes. No behavior changes inside the existing functions. Receivers on 0.1.4 work unchanged on 0.1.5.

Per the pre-1.0 policy this release publishes under the next dist-tag.
