fix(test): anchor the workflow-run fixture to now instead of a pinned epoch

test/workflow-run-watcher.test.ts pinned its fixture's newest activity at
2026-06-14T20:06:40Z and then asked getRecentRunSummaries(100000) to return
it. That argument is MINUTES, so the window is 69.4 days: the assertion
expired at 2026-08-23T06:46:40Z and the file has failed on every branch
since, on a suite nobody had touched. The last green CI run finished at
06:47:43Z, about a minute inside the boundary, which is why it landed as a
surprise rather than a bisectable regression.

The fixture epochs now hang off a RUN_ANCHOR of Date.now() - 601s with every
offset preserved verbatim, so the parsed durations, the ordering and the
live-vs-done discriminators are all unchanged, and the recency filter is
still the thing under test. It just cannot rot again.
