ci: allow the complete benchmark to finish on shared runners

 Pipelines switch to MR pipelines when a branch has an open MR, avoiding duplicate builds. Docker publication from MR pipelines is limited to detached pipelines within this project. Tag pipelines promote the already-built commit image instead of rebuilding it.
 
-The test job runs Vitest directly with at most two workers and coverage. It then runs the complete benchmark protocol separately, with one worker, a 2 GiB Node heap limit, and no coverage instrumentation, preserving its assertions and existing timeout. This avoids the benchmark's observed 90-second timeout under coverage while keeping it mandatory.
+The test job runs Vitest directly with at most two workers and coverage. It then runs the complete benchmark protocol separately, with one worker, a 2 GiB Node heap limit, and no coverage instrumentation. The benchmark uses a five-minute execution timeout to allow for shared-runner contention; all protocol assertions remain mandatory. Timing measurements are benchmark evidence, not CI performance thresholds.
