Release notes

# 0.2.0

Fixture changelog for the first signed pQRs SDK release train, standing up
CodeArtifact distribution and KMS-signed release archives for `@pqrs/paylink`,
`@pqrs/merchant`, `@pqrs/payer-flow`, `@pqrs/consumer-payee`, and `PQRSKit`
(`PaylinkKit`, `PayerFlowKit`).

This is placeholder content for the pqrs-portal Phase 0 fixture contract —
not a real release.
