Add readExtraAliasEntryOld (tag 20) and readExtraAliasEntry (tag 33)
wire readers so the node can deserialise blocks containing alias
registrations. Without these readers, mainnet sync would fail on any
block with an alias transaction. Three round-trip tests validate the
new readers.
Also apply AX-2 (comments as usage examples) across 12 files: add
concrete usage-example comments to exported functions in config/,
types/, wire/, chain/, difficulty/, and consensus/. Fix stale doc
in consensus/doc.go that incorrectly referenced *config.ChainConfig.

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.
