feat(status): auto-present while DuckStation runs

Game detection probed only gamescope and Steam, so a standalone
DuckStation session never turned presentation on. Add a third probe for
the duckstation-qt process.

pgrep -x rather than the bracketed pgrep -f the Steam path needs: this
is an exact match on the process name, so it cannot match the sh running
the check, and the binary name is under the 15 character comm limit so
it is not truncated.

 The result is written to `status.gaming`, a file separate from
 `status.presentation`, and presentation is the OR of the two. That separation
