This pull request introduces a new Tezos faucet Cloudflare Worker (src/cloudflare/faucet) with secure rate limiting, environment configuration, and documentation for deployment and usage. The main themes are the implementation of the faucet API, integration of Cloudflare Durable Objects for rate limiting, and improved configuration and documentation for production deployment.

Tezos Faucet Worker Implementation

• Added a new Tezos faucet Cloudflare Worker in src/cloudflare/faucet/index.ts, providing a /fund API endpoint that securely sends Tez to user addresses, validates input, checks rate limits, and verifies CAPTCHA via Turnstile.
• Defined strict TypeScript interfaces for requests, responses, environment variables, and Turnstile verification in src/cloudflare/faucet/types.ts.
• Created a dedicated package.json for the faucet worker with required dependencies (@taquito/taquito, @taquito/signer) and scripts for development and deployment.

Rate Limiting via Durable Objects

• Implemented a RateLimiter Durable Object in src/cloudflare/faucet/RateLimiter.ts to persistently track and enforce rate limits on faucet requests per IP address.
• Configured Durable Object bindings and migrations in src/cloudflare/faucet/wrangler.jsonc for Cloudflare deployment.

Configuration & Documentation

• Added example environment variables to .env.example and updated deployment workflow to support new secrets and configuration for the faucet and Turnstile. [1] [2]
• Provided comprehensive production deployment instructions in src/cloudflare/faucet/DEPLOYMENT.md and a quick API usage reference in src/cloudflare/faucet/USAGE.md. [1] [2]

Tooling & Dependency Updates

• Updated eslint.config.ts to ignore generated files for the faucet worker, and added vue-turnstile to the main app dependencies for CAPTCHA integration. [1] [2]
