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.

Converts the last 3 fmt.Errorf calls in production code (excluding
crypto/ CGo boundary) to coreerr.E() for conventions consistency.

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

Add full V2 transaction verification pipeline: parse SignaturesRaw variant
vector into structured ZC signature data, verify CLSAG GGX ring signatures
per ZC input, verify BPP range proofs, and verify BGE asset surjection
proofs with correct ring construction (mul8 point arithmetic).
Fix three wire format bugs that caused V2 parsing failures:
- RefTypeGlobalIndex (tag 0x1A) uses 8-byte LE, not varint
- Raw uint64_t variant (tagUint64) uses 8-byte LE, not varint
- zarcanum_tx_data_v1 fee uses FIELD() → 8-byte LE, not VARINT_FIELD()
Add cn_point_sub to C++ bridge and Go wrapper for BGE ring construction.
Add GetZCRingOutputs to chain for fetching ZC ring member data.

Implements consensus.RingOutputsFn by looking up output public keys from
the chain's global output index and transaction store. Wired into the
sync loop so VerifySignatures=true uses real crypto verification.
