Wallet Balance Watcher 🔔

🔔 Read-only wallet surveillance - watch any list of addresses (no limit) and get alerted (console/email/SMS/webhook) when one moves. Dormant mode trips on any on-chain change ("first move in N days"); active mode alerts on meaningful net value moves (threshold + cooldown); --exclude-price-moves narrows to balance-change deltas. Watches EVM, Solana, and Bitcoin (native gas, spam-filtered token index, explicit tokens; BTC = confirmed UTXO + optional --unconfirmed alerts). Flow context adds labels, transfer direction, cross-watchlist links, drain/recurring alerts, portfolio rollups, and a flow-graph. Failed deliveries are retried; no keys, no signing, no on-chain writes. Flow context is best-effort (`unknown` over a guess); portfolio rollups in USD (best-effort feed), flow amounts token-unit. Informational only - not financial advice. Limitations: no BTC flow/Ordinals/BRC-20/Runes; index-dependent coverage (--token); active mode measures net moves.
