fix(windows): keep VT enabled during progress

Windows hook installers can toggle off VT processing, which makes indicatif's progress output render as raw ANSI escape sequences.

Keep VT enabled while progress bars are active on Windows, and re-enable it after subprocess status/output calls, so install output stays readable even if a child process flips console mode.
