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.

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.

Connect crypto.CheckRingSignature() to verifyV1Signatures() so
pre-HF4 transactions have their ring signatures cryptographically
verified when a RingOutputsFn callback is provided.
