- rpc_client::callRaw: a daemon error object is no longer assumed to carry a string
"message" — a malformed error now yields a clean "RPC error: <dump>" instead of throwing
a json type-exception from .get<std::string>().
- sendTransaction (full-node): add a single-flight guard so a rapid double-click can't issue
two z_sendmany before the first returns its opid. The lite path already guarded this; the
send form guards it in the UI, but the controller entry point now does too.
(#9 from the audit was mostly false positives on verification — all popen sites already
null-check and the xmrig download FILE* path has no throwing calls. The payment-URI
checksum idea was dropped: the send flow already checksum-validates the recipient before
broadcasting, and tightening the parser would reject the placeholder addresses the existing
test relies on; added a comment noting this is format-only by design.)
