📝 [DOCS] Add Torii indexer overview

[jimenezz22]

📝 Description

Create a simplified overview documentation explaining Torii indexer and its
role in the Dojo ecosystem. Keep it concise and practical.

📚 Context

New developers need a quick understanding of what Torii is and why they need
it, without overwhelming technical details.

✅ Tasks

Torii Overview Documentation (pages/deployments/torii/overview.md)

• What is Torii?

  • Official indexing engine for Dojo worlds
  • Automatically syncs blockchain state to a database
  • Provides APIs to query game data efficiently
  • Built in Rust for performance
  • Comes pre-installed with Dojo toolchain

• Why use Torii?

  • Direct blockchain queries are slow and expensive
  • Torii indexes your game state for instant access
  • Real-time updates via subscriptions
  • Multiple query options (GraphQL, gRPC, SQL)

• How it works (simplified)

  1. Monitors your deployed World contract
  2. Captures all game state changes
  3. Stores data in local database
  4. Provides APIs for your client to query

• API Interfaces

  • GraphQL: Flexible queries with subscriptions
    • Endpoint: http://localhost:8080/graphql
  • gRPC: High-performance binary protocol
    • Endpoint: http://localhost:8080

• When to use Torii

  • Fetching player statistics
  • Building leaderboards
  • Real-time game state updates
  • Historical game data analysis

• Installation Note

  • Torii is included by default when you install Dojo
  • No separate installation needed

📋 Acceptance Criteria

• Clear, concise explanation (no overwhelming details)
• Practical examples of use cases
• Mention that Torii comes with Dojo
• Links to deployment and integration guides

🎯 Expected Outcome

A developer should understand in 2-3 minutes:

1. What Torii does
2. Why they need it
3. That it's already installed with Dojo
4. What APIs it provides

💡 Additional Notes

• Keep technical jargon to minimum
• Focus on practical benefits
• Avoid deep architecture details
• Use simple analogies if helpful

📚 References

• Dojo Book - Torii

Hello @jimenezz22 Can I take this issue?

I'm a developer with a solid background in Web3, working across both front-end and back-end. I've contributed to projects in ecosystems like StarkNet, Stellar, Optimism, and Worldcoin, with a focus on building scalable, secure, and efficient blockchain applications.

Currently, I'm a Fellow at OnlyDust and a maintainer at PayStell and StellarRent, where I lead the development of smart contracts and decentralized infrastructure.
