Aegis 0.32.3: WizardConnect waits between relay reconnects

Browse source 
When the relays were unreachable (after a sleep, or a relay offline) the
relay client reconnected with no delay at all, re-signing the queued
wallet_ready on every lap. On Theseus's main thread that spun a core for an
hour, grew the process to 2.5 GB and froze the browser. connect() now waits
2 s, 4 s ... up to 60 s between tries, and starts over once a connection
has held for a minute.

// Reconnect backoff for WizardConnect relays.
//
// RelayClient.connect() resolves as soon as the subscription is created, before
// any socket opens. When every relay is unreachable (DNS down after a sleep, a
// relay offline) the pool closes the subscription at once, the connection
// manager hears "disconnected" and calls connect() again with no delay — its
// reconnectInterval only applies when connect() throws, which it never does.
// Every lap also re-wraps the queued wallet_ready (two Schnorr signatures and
// two ECDH per relay), all on Theseus's main thread: on 2026-10-07 that spun
// one core flat out for an hour, grew the process to 2.5 GB and froze the
// browser. Delaying connect() itself throttles the loop, whoever calls it: the
// first try is immediate, then 2 s, 4 s ... up to 60 s; a connection that has
// held for a minute starts the count over.
