docs(readme): add comprehensive project documentation

[ayushtr-aws]

Summary

• Replaced the placeholder README.md (which only contained [readme]) with full, useful documentation
• Covers features, tech stack, getting started (install/dev/build/lint), project structure, teams included, and contributing guidance
• Closes SCRUM-33

Build & test results

Command	Result
mise run build	✅ Pass — 20 modules transformed, built in ~108ms
mise run lint	✅ Pass — no lint errors

Note: both build and lint were failing before this task because node_modules wasn't installed. Running npm install inside soccer-app/ was required first (no source code changes needed).

Decisions made

• Wrote documentation that describes the actual app (React/TypeScript soccer stats viewer) rather than the generic Vite template boilerplate that was in soccer-app/README.md
• Included a teams table, project structure tree, and prerequisites section so new contributors can get up and running quickly

Agent notes

What went well: The codebase is small and well-organized — a single React app under soccer-app/ with clean TypeScript. The data model (teams/players) was immediately clear from teams.ts.

What was difficult: Build and lint tools were not installed initially (tsc: not found, oxlint: not found) because node_modules was missing; a quick npm install fixed both. This is consistent with the prior episode notes about build/lint tooling issues.

Patterns discovered:

• Commit style follows conventional commits: type(module): description
• mise.toml is used as the task runner; all dev tasks run through mise run <task>
• Dependencies must be installed manually with npm install inside soccer-app/ before build/lint work

Suggestions for future tasks:

• Consider adding a mise run install task that runs npm install in soccer-app/ so the full dev setup is a single command
• The CODE_OF_CONDUCT.md is empty — a future task could fill it in
• Player data is hardcoded in teams.ts; a future task could wire up a real API
