0.7.0-rc.29 (Synonym Fork)

Bug Fixes

• Bumped FEE_RATE_CACHE_UPDATE_TIMEOUT_SECS and TX_BROADCAST_TIMEOUT_SECS from 5s to 15s.
  The 5s node-level timeout fires before Electrum can complete a request (10s timeout), causing
  FeerateEstimationUpdateTimeout on node start.
• Fixed external scores sync using spawn_background_processor_task (reserved for the single
  LDK background processor), which caused a debug_assert panic. Switched to
  spawn_cancellable_background_task.
• Fixed PeerStore::add_peer silently ignoring address updates for existing peers. When a peer's
  IP address changes (e.g., LSP node migration), add_peer now upserts the socket address and
  re-persists, instead of returning early.
• Backported upstream Electrum sync fix (PR #4341): Skip unconfirmed get_history entries in
  ElectrumSyncClient.
• Fixed duplicate payment events being emitted when LDK replays events after node restart.
• Switched from forked rust-lightning back to official upstream crates.io releases.
