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.

Add comprehensive tests exercising regular transaction processing through
the sync pipeline (key image marking, output indexing, cumulative
difficulty) and not-found error paths for all query methods. Coverage
rises from 65.8% to 80.1%.
