"""Run the MT5 Strategy Tester and wait for the report (doc 07 §3, §7).
Topology A (all-Windows): launch ``terminal64.exe /config:tester.ini`` locally.
``ShutdownTerminal=1`` makes the terminal close itself when the run finishes;
the bridge waits for the process to exit (or for the report file to appear),
then parses the report. No copy/poll step — read the HTML straight from the
terminal's report folder.
