feat(blockchain): full testnet sync, RPC daemon, wallet CLI, alias extraction
- wire: add readExtraAliasEntry (tag 33) + readExtraAliasEntryOld (tag 20) Unblocks HF4+ Zarcanum transaction deserialization - chain: alias extraction from transaction extra fields (14/14 on testnet) - chain: alias storage and retrieval via go-store - daemon: JSON-RPC server (getinfo, getheight, getblockheaderbyheight, getlastblockheader, get_all_alias_details, get_alias_details) - cmd: `chain serve` — sync from seed + serve RPC simultaneously - cmd: `wallet create` — generate keys, iTHN address, 24-word seed - cmd: `wallet address` — show base58-encoded iTHN address - cmd: `wallet seed` — show mnemonic seed phrase - cmd: `wallet scan` — scan chain for owned outputs via ECDH derivation Tested: 11,263 blocks synced in 3m11s from live testnet. All HF0-HF4 validated. 14 aliases extracted. RPC serves correct heights, difficulties, block headers, and alias data. Wallet generates valid iTHN addresses. Co-Authored-By: Charon <charon@lethean.io>
