tvOS projects based on expo cannot install react-native-purchases

Fix first: upgrade react-native-purchases to 7.26.0 or newer. tvOS support was added there (member vegaro); the reporter confirmed it runs perfectly on 7.26.0.

1. Upgrade react-native-purchases to 7.26.0+.
2. Install on the tvOS project. Expected: it installs and runs.

When to use: a tvOS project based on expo cannot install react-native-purchases.

When not to use: other platforms (they were already supported).

Compatibility: react-native-purchases 7.26.0+. Reported in RevenueCat/react-native-purchases#947.

Variants:

• "react-native-purchases tvOS"
• "revenuecat expo tvos"
• "react-native-purchases 7.26.0"

Root cause: no tvOS support before 7.26.0.

Edge cases: none; the version gate is the whole story.
