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.

Add explicit errors for unknown input/output variants in the wire encoder and tighten transparent output validation in consensus. Cover the new failure paths with unit tests.

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.

Adds target variant serialisation in both V1 and V2 output
encoders/decoders. Supports multisig (tag 0x04) and HTLC
(tag 0x23) targets within TxOutputBare.

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

Fix three bugs in the v2+ wire format and add complete variant tag handlers
for Zarcanum proof and signature structures. Verified byte-identical
round-trip against a real post-HF4 coinbase transaction from testnet block
101 (1323 bytes, tx hash 543bc3c2...3b61e0).
Bugs fixed:
- V2 suffix order was attachment+proofs, corrected to attachment+signatures+proofs
- TransactionHash was hashing full blob, corrected to prefix-only (matching C++)
- tagSignedParts was reading 4 fixed bytes, corrected to two varints
New: TxInputZC type, SignaturesRaw field, tagZarcanumTxDataV1 handler,
proof tags 46-48, signature tags 42-45, crypto blob readers for BPP/BPPE/
BGE/CLSAG GGX/GGXXG/aggregation proof/double Schnorr structures.

Add consensus-critical binary serialisation for blocks and transactions,
verified by computing the testnet genesis block hash and matching the C++
daemon output (cb9d5455...4963). Fixes Phase 0 type mismatches (variant
tags, field widths, missing fields) and adds encoder/decoder, tree hash,
and block/transaction hashing.
Key discovery: CryptoNote's get_object_hash(blobdata) prepends
varint(length) before hashing, so BlockHash = Keccak256(varint(len) || blob).
