Bitcoin Mempool Inspector

Inspect the Bitcoin mempool. With no inputs: a live congestion snapshot — pending tx count, total vMB backlog, projected blocks to clear, congestion level, the current recommended fee rates in sat/vB (next-block / 30-min / 1-hour / economy), and the fee histogram. By address: list the address's pending (unconfirmed) txs with fee, vsize, and sat/vB rate. By tx id: the transaction's fee and sat/vB rate plus a "stuck" diagnosis — its effective rate (including any CPFP child) compared against current recommended tiers, and whether RBF is signaled.
