Sync fixes:
- Extend stall detection beyond IBD to catch post-IBD sync gaps
- Walk-forward inv continuation to avoid CBlockLocator exponential gap loop
- Track walk-forward progress for stall recovery without restarting from scratch
GUI fixes:
- Load transactions synchronously in constructor (deferred QTimer never fired)
- Use beginResetModel/endResetModel instead of deprecated reset()
- Schedule full refresh on TRY_LOCK failure to avoid dropped CT_NEW notifications
- Only update cachedNumBlocks after successful balance check (prevents permanent loss)
- Add GetAllBalances() single-pass balance retrieval with TRY_LOCK
Bootstrap:
- Add trusted snapshot manifest verification for bootstrap archives
- Add IsKnownCheckpoint() to validate manifest against compiled-in checkpoints
- Skip txleveldb rebuild when verified manifest is present
Bump version to 5.3.7 across all packaging manifests.

Move GetStakeWeight() off the UI thread by caching in the staking
miner thread. Replace blocking LOCK(cs_vNodes) with TRY_LOCK in
clientmodel and staking icon updates. Fix out-of-sync label getting
stuck when disconnected. Add daemon bootstrap and faster IBD pipeline.

Major sync performance overhaul:
- Assumevalid: skip FetchInputs/ConnectInputs for blocks below
checkpoint (2,186,940). Only write txindex entries. Eliminates
millions of LevelDB reads during initial sync.
- Skip SyncWithWallets during IBD with automatic post-IBD wallet
rescan from genesis and SecureMsg chain scan.
- Skip wallet best-chain locator update during IBD so restarts
trigger proper rescan.
- Remove send/receive buffer limits (were 1MB/5MB, now unlimited).
The 1MB send buffer was the root cause of ~180 block stalls -
ProcessMessages stops reading when nSendSize >= SendBufferSize().
- Reduce IBD pipeline batch from 500 to 100 blocks for faster
re-requesting with near-instant block processing.
- Seed getblocks limit raised to 20000 during IBD (was 500).
- Faster message handler polling during IBD (10ms vs 100ms).

Critical fix: revert initial sync from getheaders back to getblocks.
The headers-first change (05b1fd1) broke chain continuation — after
downloading the first 2000 blocks, fresh nodes would stall because
the getheaders path has no orphan-based continuation mechanism.
The getblocks/inv/orphan cycle is required for full chain sync.
Also adds getblocks fallback to the headers handler so if headers
are used via other paths, sync still continues.
Other changes:
- Extract REST API into separate rest.cpp/rest.h
- Add REST rate limiting and CORS support
