- lndconnect.nix: rewrite to lnd-only (320 lines removed) - remove
services.clightning.plugins.clnrest.lnconnect and
services.clightning-rest.lndconnect (Sovran only uses services.lnd.lndconnect for Zeus)
Fixes: 'services.clightning.plugins.clnrest.address does not exist' on f13ff45
and 'attribute enable missing' at lndconnect.nix:216
- btcpayserver.nix: remove liquidd (lbtc) dead branch - Sovran uses lbtc=false
* remove inherit (config.services) bitcoind liquidd -> just bitcoind
* lbtc chains/rpc handling is dead code, keep guards but no need for liquidd service
- mempool.nix: remove fulcrum branch - Sovran uses electrs only
- rtl.nix: remove lightning-loop block and clightning service block (lnd only)
- Delete modules/bitcoin/stubs.nix entirely - no dead service references left
* liquidd, fulcrum, lightning-loop, joinmarket now not referenced at all
* clightning already handled via guards, not stubs
- Result: modules/bitcoin/ is now 100% tailored to Sovran (bitcoind+knots, lnd, electrs, rtl, btcpayserver, mempool)
No more stubs whack-a-mole on any nixos-unstable
