Fix GitHubNetworkException wrap test logic for persistent network failures

[SayanthRock]

User description

The previous test failed because postFormWithRetry caught and rethrew the exception in a way that wrapped it in multiple GitHubNetworkException layers, while the test just checked cause.cause.message.
The updated test now correctly loops through all causes to find the root IOException simulating the network failure, ensuring that the test passes reliably even if the exception is wrapped differently.

CodeAnt-AI Description

Make persistent network failure tests resilient to nested error wrapping

What Changed

• Network failure tests now inspect the full error chain to find the simulated root failure, instead of assuming a fixed wrapping depth
• The test continues to verify the user-facing network error, retry count, and wrapped exception behavior

Impact

✅ Reliable network failure test coverage
✅ Accurate validation of error messages
✅ Fewer false test failures from nested exceptions

📝 Walkthrough

Walkthrough

The persistent network failure test now traverses the full exception cause chain before asserting the root-cause message. The previous test-plan content was removed without replacement.

Changes

OAuth network failure test

Layer / File(s)	Summary
Root-cause assertion core-network/src/test/java/com/sayanthrock/rockreleasehub/core/network/auth/GitHubOAuthDeviceFlowGatewayTest.kt, test-plan.md	The test walks through nested causes until the deepest exception and verifies "Simulated network failure"; the previous test-plan instructions were removed.
