### What changes were proposed in this PR? Report per-row MainLoop failures through the worker exception path, enter exception pause, and stop consuming the affected batch. Before: the worker logged the failure, continued later rows, and could finish with missing output. After: the coordinator receives the error and the batch stops at the failed row. ### Any related issues, documentation, discussions? Closes #8297 ### How was this PR tested? Added a regression covering the failure report, exception pause, and stopped batch consumption. ```powershell $env:PYTHONDONTWRITEBYTECODE='1'; C:\Users\carlo\texera\texera\.venv312\Scripts\python.exe -c "import sys,pytest; sys.path[:0]=[r'C:\Users\carlo\texera\texera-worktrees\investigate-bug78\amber\src\main\python',r'C:\Users\carlo\texera\texera\amber\src\main\python']; raise SystemExit(pytest.main([r'amber/src/test/python/core/runnables/test_main_loop.py::TestMainLoop::test_failing_element_reports_exception_and_stops_batch','-p','no:cacheprovider','-q']))" C:\Users\carlo\texera\texera\.venv312\Scripts\ruff.exe check amber/src/main/python/core/runnables/main_loop.py amber/src/test/python/core/runnables/test_main_loop.py C:\Users\carlo\texera\texera\.venv312\Scripts\ruff.exe format --check amber/src/main/python/core/runnables/main_loop.py amber/src/test/python/core/runnables/test_main_loop.py ``` The focused regression passed. The full MainLoop test file was also run: 36 tests passed and 8 pre-existing integration cases failed during executor initialization because the shared generated protocol files do not yet contain `loop_start_port_uris`. ### Was this PR authored or co-authored using generative AI tooling?
