ci: convert integration test to multi-cycle benchmarking tool

Update .gitea/workflows/t.yaml to perform four sequential test cycles:
   1. Baseline (original state)
   2. After cherry-picking 572e3311 (CP1)
   3. After cherry-picking 8fa732e6 (CP1 + CP2)
   4. After discarding previous CPs and cherry-picking 58f410be

   Each cycle runs test_005_any_maintainer_approval_sufficient 30 times
   to gather pass/fail statistics for performance and stability comparison.
