//! # Interactive Mode
//!
//! `scope interactive` (also `scope tui` and `scope shell`) opens the
//! unified TUI in [`crate::cli::tui`]. This module keeps its arguments and
//! the [`SessionContext`] that persists between commands. The chain
//! defaults to `auto`, meaning each command infers the chain from its
//! input (e.g., `0x…` → Ethereum/EVM, `T…` → Tron, base58 → Solana).
//! Users can pin a chain with `chain solana` and unlock with `chain auto`.
//!
//! ## Usage
//!
//! ```bash
//! scope interactive
//!
//! scope:auto> address 0x742d35Cc6634C0532925a3b844Bc9e7595f1b3c2
//! # Chain: ethereum (auto-detected)
//!
//! scope:auto> address DRpbCBMxVnDK7maPM5tGv6MvB3v1sRMC86PZ8okm21hy
//! # Chain: solana (auto-detected)
//!
//! scope:auto> chain solana
//! # Chain pinned to: solana
//!
//! scope:solana> address 7xKXtg...
//! # Uses solana chain
//! ```
