A reply line over asyncio's default 64 KiB StreamReader limit raised out of
_read_loop and closed the only connection; the pool address's get_history passes
that after ~800 transactions, and dust sent to any public address does it on
purpose.
- ElectrumClient opens the stream with a 16 MiB limit and frames lines itself:
an oversized line is discarded up to its newline, a non-JSON line is dropped,
and the request whose id is readable in the first/last 256 bytes fails at once;
the connection stays up either way.
- Coins below DUST_LIMIT_SATS are never offered as credit candidates, never
credited, and select_utxos never selects them.
- Spec (ELC-20, DEP-01, DAT-10, ARC), storico, BUGS.md and test counts updated.
