feat: add comprehensive session error regression tests to prevent modal failures
Add 10 new regression tests in Section 10 targeting specific errors encountered:
🚨 Session Error Prevention:
- Async generator wrapper validation (prevents "not iterable" errors)
- Dynamic import wrapper error handling (prevents undefined function errors)
- Module import path verification (prevents wrong module imports)
- Variable scope isolation (prevents direct chatHistory access)
- Runtime function availability (prevents window.function undefined errors)
- Module export consistency (prevents import/export mismatches)
- Async/await pattern validation (prevents promise handling errors)
- Error boundary patterns (prevents cascading failures)
- Generator function delegation (prevents yield* delegation errors)
- Function signature compatibility (prevents parameter mismatches)
These tests specifically target the JavaScript errors we encountered:
- sendMessageWithCustomHistory(...) is not iterable
- fetchModelsFromEndpoints is not a function
- loadConversationHistory is not a function
- clearConversationHistory is not a function
- saveConversationHistory is not a function
- getSelectedModel is not a function
- chatHistory is not defined
- window.openTTSModal is not a function
- window.openTranslateModal is not a function
All tests validate current fixes and prevent regression of these specific patterns.
