optionsoverlay: add D293 quit-to-desktop row to the F10 overlay

No discoverable in-UI way to quit (Deck/controller-only setups had only
window-close/Alt+F4). Adds a ROW_ACTION row kind (not config-backed, same
pattern as the existing __Resolution row) that triggers the identical
configSave()+exit(0) path SDL_QUIT already uses. Build-verified on Windows
and Linux; verify.sh dam PASS, no regression.

D255's mechanism is generic to computer-terminal props, not Facility-specific, so a Dam terminal hitting the same bug is plausible and would already be fixed by the same patch. **Not yet confirmed** which build the user was on when this happened (pre- or post-D255-fix) — if it was pre-fix, this is very likely just D255 and needs no separate investigation; if it recurs on a build that has the D255 fix, that's a new, real, distinct bug worth its own crash log.
 
-**Status (from §F table):** OPEN — needs a human re-test specifically on a build with the D255 fix (this session's `release/v0.3.0`, not any earlier build) to see if it still happens. If it does, get `ge007.crash.log` (or a gdb `bt full` under `debug.ps1`) and the exact terminal/action — that's the actionable next step, not further static analysis.

 **QoL ask: no discoverable way to quit the game from the UI (M-141, Steam Deck user playtest — "couldn't see a way to exit the game. Maybe build this into the settings/options menu.").** Confirmed in code: the only quit path is `SDL_QUIT` (`port/src/video.c:515`, the OS window-close event / Alt+F4) — there is no Escape-key handler and no "Quit" entry in the front-end menus or the F10 options overlay. Fine on a desktop with visible window chrome; a real gap on Steam Deck / controller-only / fullscreen setups with no easy way to reach the OS window controls.
 
-**Status (from §F table):** OPEN — not investigated, low complexity. Candidate fix: a "Quit to Desktop" row in the F10 overlay (`port/src/optionsoverlay.c`) and/or an Escape-key binding in the front-end menu context (`port/src/input.c`), calling the same path `SDL_QUIT` already triggers. Cheap, port-only, good QoL-batch candidate.
+**Status (from §F table):** FIXED (M-141, `release/v0.3.0` local). Added a "Quit to desktop" row to the F10 overlay (`port/src/optionsoverlay.c`) — a new `ROW_ACTION` kind (not config-backed, same non-config pattern as the existing `__Resolution` row) that calls the identical `sysLogPrintf` + `configSave()` + `exit(0)` path `SDL_QUIT`/Alt+F4 already use. Reachable by keyboard (arrow/Enter when the row is selected), mouse click, or gamepad A/X — no new Escape binding was added (D145 already dedicates ESC to menu-back / cursor-release). Build-verified on Windows (`ninja`, clean link) and Linux (WSL `Ubuntu-24.04` cross-build); `tools_pc/verify.sh dam` PASS, no regression. **Not yet live-confirmed** — needs a human to actually select the row on a real session (headless/SSH-launched smoke tests can't reach the Deck's own X/gamescope display to drive input).
