Migrate types/asset.go from fmt.Errorf to coreerr.E() for consistency
with the rest of the types package. Add usage-example comments (AX-2) to
all key exported functions in consensus/, chain/, and types/ so agents
can see concrete calling patterns without reading implementation details.

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.

Replace all fmt.Errorf and errors.New in production code with
coreerr.E("Caller.Method", "message", err) from go-log. Replace
os.MkdirAll with coreio.Local.EnsureDir from go-io. Sentinel errors
(consensus/errors.go, wire/varint.go) intentionally kept as errors.New
for errors.Is compatibility.
270 error call sites converted across 38 files. Test files untouched.
crypto/ directory (CGO) untouched.
