Google Play Billing `v7` to `v8` migration guide, with `v9` prep

This is less about new features than forced maintenance: removed APIs, flow changes, and version-specific behavior shifts can break Android revenue paths. Relevant if you ship subscriptions or IAPs on Google Play; otherwise low priority.

[ KEY POINTS ]
  1. Covers the migration timeline from v7 to v8, so billing SDK upgrades now have scheduling risk, not just code churn.
  2. Removed APIs and their replacements are called out directly; old purchase code paths may stop being safe to carry forward.
  3. Connection, query, and purchase flows were updated, which means regression testing has to include the full checkout lifecycle.
  4. It also flags v8 to v8.3 behavior changes and v9 prep, so upgrading once and freezing is the wrong move.
