Centralise handshake response validation so outbound sync checks both network identity and minimum peer build version through the p2p layer. Also record HTLC key images as spent during block processing, matching the HF1 input semantics and preventing those spends from being omitted from chain state.

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.

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.

The block processing logic is now in processBlockBlobs() which takes
raw wire bytes. The RPC processBlock() becomes a thin hex-decode
wrapper. The P2P sync path will call processBlockBlobs() directly.

The Zano daemon's get_blocks_details RPC does not populate the blob
field. This adds resolveBlockBlobs() which batch-fetches miner tx
blobs via /gettransactions and reconstructs block wire blobs from
the parsed header (object_in_json AGGREGATED section) and raw tx
bytes. Also fixes regular tx processing to skip the miner tx entry
that the daemon includes in transactions_details.

TxInputZC (v2+) inputs have key images that must be tracked for
double-spend detection, same as TxInputToKey.

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.
