The NIP-46 login dialog is purely the QR / connect-link flow ("scan with Amber/
NsecBunker"), but it failed with "A remote signer pubkey is required." A
nostrconnect:// link carries the CLIENT pubkey; the remote signer's pubkey is
only learned after it scans the QR and acknowledges — and the active connect
path (SignerManager) only supported bunker:// (pubkey already in the URI). The
"wait for the signer to acknowledge" logic existed only on the unused
Nip46Connector.
Port it into SignerManager as _waitForRemoteSignerHandshake: subscribe to
kind-24133 events addressed to the client pubkey, decrypt the signer's response,
match the handshake secret (or a generic ack), surface auth_url challenges, and
resolve with the signer's pubkey (with a timeout + a cancel hook wired into
disconnectRemoteSigner). connectRemoteSigner now performs this wait for
client-initiated (nostrconnect) connections before constructing the RPC client;
bunker:// is unchanged.
Decryption uses the existing attemptDecryptNip46HandshakePayload (injectable via
_decryptHandshakePayload for testing). Test: tests/nostr/nip46-wait-handshake.test.mjs
(secret match resolves with signer pubkey; wrong secret ignored -> timeout;
auth_url surfaced without resolving). Full suite green.
