scope-bca 0.8.3

//! # Scope Blockchain Analysis
//!
//! Entry point for the blockchain analysis command-line tool.
//!
//! This binary provides commands for:
//!
//! **Entity lookup:**
//! - Address analysis (`scope address` / `addr`) with `--report` and `--dossier`
//! - Transaction analysis (`scope tx` / `transaction`)
//! - Unified insights (`scope insights` / `insight`) — auto-detects target type
//!
//! **Token analysis:**
//! - Token crawling (`scope crawl` / `token`) with report generation
//! - Token health suite (`scope token-health` / `health`) — DEX + optional market
//! - Token discovery (`scope discover` / `disc`) — trending/boosted from DexScreener
//! - Live monitoring (`scope monitor` / `mon`) — real-time TUI dashboard
//! - Market peg/order book health (`scope market summary`)
//!
//! **Compliance:**
//! - Risk, trace, analyze, and compliance-report (`scope compliance`)
//!
//! **Data & export:**
//! - Address book management (`scope address-book` / `ab`, alias: `portfolio` / `port`)
//! - Data export (`scope export`)
//! - Batch reporting (`scope report batch`)
//!
//! **Config & interactive:**
//! - Interactive mode (`scope interactive` / `shell`)
//! - Setup wizard (`scope setup` / `config`)
//! - Shell completions (`scope completions bash|zsh|fish`)
//!
//! ## UX Features
//!
//! - **Progress indicators** — Spinners and progress bars for long-running operations
//! - **Error remediation hints** — Actionable suggestions for common errors
//! - **Typo suggestions** — "Did you mean?" for misspelled commands
//! - **Shell completion** — Tab-completion for bash, zsh, and fish
//! - **Help with examples** — Example invocations in `--help` for every command
//! - Global `--ai` flag forces markdown output for agent/LLM parsing
//!
//! ## Usage
//!
//! ```bash
//! scope --help
//! scope address 0x742d35Cc6634C0532925a3b844Bc9e7595f1b3c2
//! scope tx 0xabc123...
//! scope insights 0xabc123...
//! scope discover --source boosts --chain ethereum
//! scope market summary USDC --format json
//! scope token-health USDC --with-market
//! scope monitor USDC --chain ethereum
//! scope address-book list
//! scope report batch --addresses 0x... --output report.md --with-risk
//! scope completions zsh > ~/.zfunc/_scope
//! ```
