//! # Templar Funding Bridge
//!
//! NEAR-centric treasury management service for cross-chain operations.
//! Integrates with NEAR Intents Bridge API to enable cross-chain deposits and withdrawals.
//!
//! ## Features
//!
//! - **Cross-chain withdrawals** via NEAR Intents (NEP-413 signed intents)
//! - **Deposit address generation** for external chains (Ethereum, Arbitrum, Solana, etc.)
//! - **Token registry** with automatic OMFT token ID resolution
//! - **NEAR treasury management** - holds OMFT tokens, withdraws to any chain
//! - **Stateless design** - no database, all state on-chain
//!
//! ## API Endpoints
//!
//! - `GET /health` - Service health check
//! - `GET /metrics` - Prometheus-compatible metrics
//! - `GET /tokens/lookup?asset=USDT&chain=ethereum` - Resolve OMFT token IDs
//! - `POST /deposit` - **Automated deposit from external wallet** (ETH/Arbitrum)
//! - `POST /withdraw` - Initiate cross-chain withdrawal via NEAR Intents
//!
//! ## Quick Start
//!
//! ```bash
//! # Start the service (dry-run mode)
//! funding-bridge \
//!   --network mainnet \
//!   --near-treasury-account your-treasury.near \
//!   --near-treasury-key "ed25519:..." \
//!   --port 3000 \
//!   --dry-run
//! ```
