Build participant-facing Parcel Society UI

[Spbd1]

Motivation

• Provide a simple, participant-focused web UI so players can read a short tutorial, pass a comprehension check, join waiting research servers, and play the parcel game in a clear round-by-round dashboard.
• Gate joining so participants must pass a stored comprehension check before joining a server to ensure basic understanding prior to participation.
• Surface essential game state and per-player summaries so participants can make informed decisions and review round/final outcomes.

Description

• Added participant pages and flows: / landing (reworked content), /tutorial, /comprehension-check (client UI), /join, /game/[serverId] (dashboard), /game/[serverId]/summary, and /game/[serverId]/final, plus simple responsive layout and Tailwind styling.
• Implemented client helper requestJson and UI features including a 10x10 map with highlighted player parcel, action panel with AP tracking and validation, contract target/amount inputs, loading and error states, and passed/fail feedback for the comprehension check.
• Added server-side API endpoints and schema updates: api/comprehension-check (persist answers), api/join-server (now checks for a passed comprehension check), api/servers/[serverId]/state, api/servers/[serverId]/round-summary (enriched), and api/servers/[serverId]/final-summary, and a new comprehensionCheckSchema in lib/api/schemas.ts.
• Minor layout and content updates to app/layout.tsx and app/page.tsx to route the participant flow and surface Join/Tutorial links.

Testing

• Ran git diff --check which reported no problems.
• Attempted dependency install with pnpm install, but it failed due to the environment returning a 403 Forbidden from the npm registry for eslint, preventing node_modules installation.
• Ran pnpm --filter @parcel-society/web typecheck, pnpm --filter @parcel-society/web lint, pnpm --filter @parcel-society/web test, and pnpm --filter @parcel-society/web build, all of which could not complete because required dependencies were not installed; typecheck produced many module/JSX errors primarily because node_modules is missing in this environment.
