Overview

One watch session: accept report connections in the background, poll the tracked set for changes, re-run tests on save (selecting over the recorded test map when the report carries one), and push a reload to every open tab when the report regenerates.

MERGE_WINDOW =

The merge window the child runs get through SIMPLECOV_MERGE_TIMEOUT: a day, so subset re-runs keep merging into a whole report across a long session instead of eroding it after the default ten minutes.
