Replace the previous frontend workflow with an expanded Build, Test & Push workflow. Adds a quality-check job (runs on push and PRs to main) that sets up Node.js, installs deps, runs lint/type checks, unit tests (ChromeHeadless), production build and runs LHCI. The docker job now depends on the quality-check job and only runs on pushes to main. Added lighthouserc.json and ignored .lighthouseci, relaxed two ESLint rules (@typescript-eslint/no-inferrable-types and no-explicit-any), and updated package.json (and lock) to include LHCI tooling.
Conway GOL: add executionTime tracking and display; switch to double-buffered read/write grids with structuredClone initialization; refactor life update logic (checkLifeRules, swapGrids) to avoid mutating the source while computing the next generation; adjust per-frame delay to account for execution time; increase MAX_GRID_SIZE from 100 to 200; fix grid binding to use readGrid so UI reflects internal state.
Generic grid: add backgroundColor input and use it to clear canvas each frame; only draw cells whose color differs from background and draw grid lines conditionally based on node size to reduce overdraw; adjust drawNode to only stroke borders for larger nodes.
Templates: set backgroundColor='lightgray' for Conway and Pathfinding grid usages; display execution time in Conway UI.
Misc: remove a debug console.log in sorting component. These changes improve rendering performance, reduce flicker, and surface per-frame timing for tuning the Game of Life simulation.
