Add an in-game exit confirmation modal for Playing state: ESC opens modal and pauses the game; YES resets and returns to Menu; NO hides modal and resumes. Draw a full-window translucent dim background (reset viewport) so overlay covers any window size / fullscreen. Use PressStart2P (pixel P2) font for all modal text and center title/body/button labels using measured text widths. Add FontAtlas::measure(...) to accurately measure text sizes (used for proper centering). Ensure popup rendering and mouse hit-testing use the same logical/content-local coordinate math so visuals and clicks align. Add keyboard shortcuts for modal (Enter = confirm, Esc = cancel) and suppress other gameplay input while modal is active. Add helper scripts for debug build+run: build-debug-and-run.ps1 and build-debug-and-run.bat. Minor fixes to related rendering & state wiring; verified Debug build completes and modal behavior in runtime.
