Local Dev 7931d981aa feat(theseus/siawallet): bundled Siacoin wallet add-on (walletd-backed, v2)
Second bundled wallet, same shape as bchwallet:
- keys: api.vault.derive("siawallet/mainnet/0") as the seed for walletd's
  KeyFromSeed(seed, index) (blake2b(seed||index) -> ed25519); addresses are
  standard unlock hashes, so a future walletd seed import yields the same
  addresses. Seed and keys live in memory only.
- lib/sia.js: Sia binary encoder, StandardUnlockHash, address checksum,
  v2 InputSigHash ("sia/sig/input|" + replay byte 2 + transaction
  semantics), transaction weight, walletd JSON. Address hashing and the
  sighash were verified against real mainnet v2 transactions (signatures
  from block 591853 verify under this implementation).
- lib/walletd.js: address-scoped walletd HTTP client (tip, fee, balance,
  outputs with proofs, events, broadcast). The node URL is a user setting
  with no default; hosted providers embed the access key in the path, so
  only the origin is ever displayed or logged.
- lib/wallet.js: gap-limit discovery via events, mature/immature balance,
  history deltas from v1/v2/foundation/miner events, largest-first
  selection with change to the current address, fee = walletd rate x
  weight x 1-3 multiplier, broadcast with the outputs' basis. A signed tx
  built here was accepted structurally by a live walletd (rejected only
  for the stub key not owning the parent).
- panel: Receive (QR), Send, History, Settings (node URL, derivation info,
  seed reveal behind approval, connected sites); gates for locked vault,
  no vault, no node URL.
- window.siacoin dapp bridge: getAddress (rememberable), signAndSend with
  100/1,000/10,000 SC allowances, signMessage (ed25519 over blake2b-256 of
  the message) — same approval and permission rules as the BCH wallet.
