3579c10196 Merge pull request #147 from ZacharyHampton/feature/ios-mobile-headers
Improve API stability and reliability
2025-12-05 19:30:25 -08:00
Zachary Hampton
f5784e0191 Update to iOS mobile app headers for improved API stability
- Replace browser-based headers with iOS mobile app headers
- Update GraphQL query names to match iOS app conventions (1:1 alignment)
- Add _graphql_post() wrapper to centralize GraphQL calls with dynamic operation names
- Simplify session management by removing unnecessary thread-local complexity
- Add test_parallel_search_consistency test to verify concurrent request stability
- Bump version from 0.8.6b to 0.8.7

Changes fix API flakiness under concurrent load - parallel consistency test now passes 100% (5/5 runs).
