Bitflash: fair-launch release

Satoshi's bitcoin-0.1.0 reborn with RandomX CPU proof of work, anonymous .btf
addressing over Nostr with CGNAT rendezvous, automatic peer discovery, a
headless Linux node, and Windows GUI wallet. Fair launch, no premine, 21M cap.

+// node publishes a replaceable event (NIP-78, kind 30078) containing its
+// "ip:port", signed with Schnorr/secp256k1 (BIP340, the same scheme used by
+// Nostr), and subscribes to receive the announcements of other nodes, feeding
+// them into the Bitflash address manager.
