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.

Prepares for HF1 output target types (TxOutMultisig, TxOutHTLC).
All call sites updated to type-assert TxOutToKey where needed.
Modified files:
- types/transaction.go: TxOutputBare.Target is now TxOutTarget
- wire/transaction.go: encode/decode use type switch on target
- chain/ring.go: type-assert target to TxOutToKey for key extraction
- wallet/scanner.go: type-assert target before key comparison
- tui/explorer_model.go: type-assert target for display
- wire/transaction_test.go: type-assert in assertions
- wallet/builder_test.go: type-assert in assertions

Builder interface with V1Builder that constructs signed v1 transactions.
Handles change outputs, ECDH output key derivation, ring construction
with sorted global indices, and NLSAG signing per input.

RingSelector interface with RPCRingSelector that fetches random outputs
from the daemon, excludes the real output and duplicates, and returns
the requested ring size.

Scanner interface with V1Scanner implementation for v0/v1 transactions.
Derives ephemeral keys via ECDH, generates key images, and tracks
coinbase status and unlock times.

GenerateAccount, RestoreFromSeed, RestoreViewOnly with deterministic
view key derivation (sc_reduce32(Keccak256(spend_secret))), matching
C++ account_base::generate(). Encrypted persistence via Argon2id
(time=3, mem=64MB) + AES-256-GCM in go-store.
Adds cn_sc_reduce32 to the CGo bridge for scalar reduction mod l,
required to convert a hash output into a valid Ed25519 secret key.

Parses tags 22 (tx public key), 14 (unlock time), and 11 (derivation
hint) from raw extra bytes. Unknown tags are skipped. Raw bytes preserved
for round-tripping.
Adds PublicKey.IsZero() to types package.
