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.

Migrate from stdlib flag to cli.Main() + WithCommands() pattern:
- AddChainCommands() registration with persistent --data-dir/--seed/--testnet flags
- Explorer subcommand (TUI block explorer, replaces old default mode)
- Sync subcommand with headless foreground and --daemon/--stop modes
- sync_service.go extracts syncLoop/syncOnce from old main.go
- cmd/core-chain/main.go standalone binary entry point
- Add go-process dependency for daemon lifecycle
