Replaces lncm/bitcoind, which pins Core 26 — a version that still has legacy wallets, while the code that talks to it (bt's BitcoindClient) is written for the descriptor-only behaviour of 29 and later. The binaries are the official release build, verified by SHA-256 in the same layer that downloads them; a version bump that forgets the checksum fails the build instead of shipping something unverified. uid 1000 and /data/.bitcoin are kept from the image this replaces, so an existing named volume survives the switch without a recursive chown of a synced chain. Verified on testnet2: regtest node healthy in ~12 s, descriptor wallet, 101 blocks mined, sendtoaddress accepted — the last one being the check for BITCOIND_FALLBACKFEE, without which a fresh chain refuses to send.
