bounded-work's largest diffFlowchart case runs close to the default test timeout under coverage #42

packages/core/graph/projection/src/bounded-work.unit.test.ts asserts work counts, but each case still runs under Vitest's default per-test timeout, and the largest cases are close to it under coverage instrumentation in CI. "diffFlowchart reading an unchanged flowchart of diamonds sharing a run half of which leads somewhere" passes on recent main runs but timed out in https://github.com/ExaDev/process-graph/actions/runs/38111508236 on #41, where the Test job also builds and tests the bundled process-graph package alongside it, and the same file timed out under the pre-push hook on a loaded machine while passing when run alone.

The property is about work, so the failure is the clock: the case's input size or its timeout needs to come from the work it does rather than the default.
