This pull request improves test execution efficiency by replacing real-time waits in several slow tests with deterministic synchronization, moving shard-safe tests onto
pytest-xdist, and isolating Redis/Dapr-sensitive files onto a serial lane that still runs automatically as part ofmake tests. Across three measured warm-cache runs after one warm-up run on the same machine,make testsaveraged 53.59 seconds before these changes and 14.34 seconds after them, reducing wall-clock time by 39.25 seconds (73.2%) and delivering about a 3.7x speedup.The change also trims unnecessary tracing fixture startup work in
tests/conftest.py, keeps overall test breadth intact, and updates CI so coverage is collected on a single Python version while the rest of the matrix uses the faster test path. Behaviorally,make coverageremains unchanged, tests markedserialstill run by default.
