Port of f3e25de from preserve/lux-bridge-golive onto main's
architecture. A BTC release now parks in
bridge_transfer_pending_confirmation on mempool admission and only
completes once mined; a release unconfirmed past --btc-confirm-timeout
(or fee-rejected at submit) is reset for re-sign at a bumped RBF
feerate — PreSign takes MinFeeRateSatPerVB as a floor over the live
estimate, and the paid rate persists on the swap (LastFeeRate) so each
rebuild strictly out-bids the last (BIP-125). Rebuild cycles share one
ceiling (default 5); past it the swap fails loudly. The broadcast
client answers confirmation status from the same mempool.space base it
posts to; /metrics gains bridge_btc_confirm_checks_total /
_timeouts_total / bridge_broadcast_rebuilds_total.
