• ASB+CONTROLLER: New set-external-bitcoin-redeem-address command with parameter address (string) allows you to udpate the external bitcoin redeem address at runtime.
  The change is persisted to the config file. Go back to using the internal Bitcoin wallet by using clear-external-bitcoin-redeem-address.

• GUI: Exolix has become a community supporter. They support development and provide a reliable market maker. They are visually highlighted in the UI.

• ASB: New maker.btc_redeem_fee_multiplier config option (default 1.0) that scales the estimated BTC redeem fee. Setting it higher (e.g. 2.0) acts as a safety margin so the redeem still confirms when fee estimation undershoots actual mempool conditions.

• ASB+CONTROLLER: get-swaps now includes the btc_redeem_txid per swap: the Bitcoin redeem transaction id. This is deterministic from the swap's locked state, so it is set even before the redeem transaction is published.

TESTING RELEASE: Concurrent swaps

Built from commit 21dfabe837e19dd1610f3bb21753c8b868f42076 by @binarybaron.

This is a developer test build. Docker images were NOT pushed to
ghcr, binaries were NOT uploaded to crabnebula, the Homebrew
formula was NOT updated, and the Flatpak repo was NOT republished.
Do not distribute this build to end users.

• ASB+CONTROLLER: get-swaps now accepts optional limit and offset parameters which can be used for pagination.
  If not present, no pagination will be done.

• ASB+CONTROLLER: get-swaps now includes the btc_redeem_fee per swap: the fee Alice paid (or will pay) for the Bitcoin redeem transaction.
• GUI+ASB: New intermediate states around Monero redeem/refund. The signed transaction is now built and published as separate steps: XmrRedeemConstructed and XmrRedeemPublished (Bob/GUI), and XmrRefundTxConstructed and XmrRefundTxPublished (Alice/ASB). The GUI surfaces both phases — "constructing", then "publishing", then waiting for the first confirmation with the redeem txid shown.
