//! # Interactive Mode
//!
//! This module implements an interactive REPL for the Scope CLI where
//! context is preserved between commands. Users can set a chain once
//! and subsequent commands will use it automatically.
//!
//! ## Usage
//!
//! ```bash
//! scope interactive
//!
//! scope> chain solana
//! Chain set to: solana
//!
//! scope> address 7xKXtg...
//! # Uses solana chain automatically
//! ```

  address <addr>    Analyze an address (uses current chain/format)
  addr              Shorthand for address
  tx <hash>         Analyze a transaction (uses current chain/format)
  crawl <token>     Crawl token analytics (holders, volume, price)
  token             Shorthand for crawl
  monitor <token>   Live-updating charts for a token (TUI mode)
  mon               Shorthand for monitor

Token Search:
  crawl USDC        Search for token by name/symbol (interactive selection)
  crawl 0x...       Use address directly (no search)
  tokens            List saved token aliases
  tokens recent     Show recently used tokens
  tokens add <sym> <chain> <addr> [name]    Add a token alias
  tokens remove <sym> [--chain <chain>]     Remove a token alias

Portfolio Commands:
  portfolio add <addr> [--label <name>] [--tags <t1,t2>]
  portfolio remove <addr>
  portfolio list
  portfolio summary [--chain <name>] [--tag <tag>] [--tokens]

Configuration:
  setup             Run the setup wizard to configure API keys
  setup --status    Show current configuration status
  setup --key <provider>    Configure a specific API key
  config            Alias for setup

Inline Overrides:
  address 0x... --chain=polygon --tokens
  tx 0x... --chain=arbitrum --trace --decode
  crawl USDC --chain=ethereum --period=7d --report=report.md

Live Monitor:
  monitor USDC      Start live monitoring with real-time charts
  mon 0x...         Monitor by address
  Time periods: [1]=15m [2]=1h [3]=6h [4]=24h [T]=cycle
  Chart modes: [C]=toggle between Line and Candlestick
  Controls: [Q]uit [R]efresh [P]ause [+/-]speed [Esc]exit
  Data is cached to temp folder and persists between sessions (24h retention)

Tips:
  - Search by token name: 'crawl WETH' or 'crawl "wrapped ether"'
  - Save aliases for quick access: select a token and choose to save
  - Context persists: set chain once, use it for multiple commands
  - Use Ctrl+C to cancel, Ctrl+D to exit
