DanSandClaude Opus 4.8 2bab58c6d2 lightwalletd: adaptive reorg-lag tip + non-blocking startup coinsupply
Adaptive-lag: advertise a tip that trails the real tip by a reorg-rate-driven
lag (GetLatestBlock/GetLightdInfo) so wallets anchor shielded spends at a
settled height during reorg churn. Configurable via
-adaptive-lag/-lag-min/-lag-max/-lag-window; monitor_lwd.sh runs
-lag-min 4 -lag-max 12 -lag-window 30.

Startup coinsupply: the informational startup coinsupply RPC (result used only
for a log line) blocked the gRPC bind for minutes on a node whose supply index
is cold, keeping the lite endpoint down on every restart while it also starved
the block-cache ingestor. Run it in a goroutine so the bind is never blocked;
clients still get coinsupply on demand via the GetCoinsupply RPC.

DanSandClaude Opus 4.8 b1b0d4559b feat(frontend): implement GetMempoolStream for 0-conf lightwallet txs
The CompactTxStreamer service did not implement any mempool RPC, so
lightwallets (SilentDragonXLite / ObsidianDragonLite) received UNIMPLEMENTED
from get_mempool_stream and permanently stopped their mempool monitor. As a
result the lite wallet could not see 0-confirmation transactions and only
surfaced incoming shielded chat messages after they were mined (~1 block).

Add GetMempoolStream(Empty) returns (stream RawTransaction). A single
process-wide monitor (frontend/mempool.go) polls the node's getrawmempool and
fetches each new tx via getrawtransaction (full serialized bytes, so shielded
memos are preserved -- CompactTx's 52-byte prefix would not carry a memo), then
fans the tx out to every subscribed stream. This avoids polling the node once
per connected wallet: N clients share one poll loop. The monitor starts lazily
on the first subscription, idles without touching the node when no clients are
connected, and closes all subscriber streams when a new block is mined (the
semantics the client's monitor loop expects; the client re-syncs and reconnects).

Purely additive and wire-compatible: RawTransaction field numbers and the
cash.z.wallet.sdk.rpc package match the deployed client; existing clients that
never call GetMempoolStream are unaffected.

DanS ebc38c9369 Fix lightwalletd sync loop for DragonX wallet
- Handle missing Sapling upgrade in getblockchaininfo response by
  defaulting activation height to 1 (DragonX has Sapling active from
  genesis but uses NO_ACTIVATION_HEIGHT in chainparams)
- Override consensus branch ID to Sapling (76b809bb) when node reports
  Sprout (00000000) due to disabled activation heights
- Include full serialized block header in CompactBlock so the SDK can
  validate hashFinalSaplingRoot against the Sapling commitment tree
- Set CompactBlock ProtoVersion to 1
