Build initial playable Code Kingdom web MVP

[mwk28]

Motivation

• Turn the Code Kingdom concept into a lightweight, playable browser MVP to validate core mechanics and iterate on gameplay.
• Provide an interactive demo that maps coding behaviors (solve/explain/study) to in-game systems like army, walls, library, and morale.
• Create a local, easy-to-run preview so designers can test balance and UX quickly.

Description

• Add index.html which implements a single-page UI with panels for player kingdom stats, battle actions, rival scouting, and a chronicle log.
• Add style.css to provide a dark, responsive layout and styled stat cards, action buttons, and log presentation.
• Add script.js that implements game state, generateEnemy, applyAction, launchAttack, rendering, and a short battle-resolution formula tying coding actions to unit generation and defense.
• Update README.md to document the game concept, attributes, attack system, included MVP features, and local run instructions.

Testing

• Ran node --check script.js to validate JavaScript syntax, which completed successfully.
• Launched a local static server using python3 -m http.server 4173 and confirmed the server served the app.
• Automated browser load via Playwright to open http://127.0.0.1:4173 and captured a full-page screenshot artifact to validate rendering, which succeeded.
