Update go.mod module line, all require/replace directives, and every .go import path from forge.lthn.ai/core/go-blockchain to dappco.re/go/core/blockchain. Add replace directives to bridge dappco.re paths to existing forge.lthn.ai registry during migration. Update CLAUDE.md, README, and docs to reflect the new module path.
