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).

Adds CTorProcess which finds and launches an external Tor binary as a
subprocess, providing a SOCKS5 proxy on port 19099 and a v3 hidden
service on port 24112. The wallet auto-detects Tor from common install
locations or the app directory. Falls back gracefully to clearnet-only
if Tor is not found. Also fixes Tor-only network restriction that
blocked IPv4/IPv6, and bumps version to 5.1.7.

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

The wallet was freezing on "Verifying database integrity" because the
old Tor v2 startup code blocked on a mutex (wait_initialized) and
required an onion/hostname file that no longer existed after v2 removal.
Replace the blocking v2 startup with internal V3 onion identity:
- Every wallet now auto-generates Ed25519 keys and a V3 .onion address
- Keys are stored in wallet.dat (encrypted if wallet is encrypted)
- Onion identity is created after wallet loads (Step 8.5) so keys
persist across restarts
- No external Tor process required for identity generation
- Writes onion/hostname and tor_data/ config for optional external Tor

Startup optimization (fixes multi-minute hang on 2M+ block chain):
- Skip computing SHA-256 stake modifier checksum for blocks below last
checkpoint (was doing 2M+ unnecessary hashes on every startup)
- Reduce default -checkblocks from 2500 to 50 (disk read savings)
- Add progress percentage reporting during block index load
Headers-first sync (faster initial sync):
- Switch initial sync from getblocks to getheaders protocol
- Add PushGetHeaders and headers message handler in net/main
- Downloads 80-byte headers first, then requests blocks — allows
the node to learn chain structure before downloading full blocks
Address-index accelerated wallet rescan:
- New ScanForWalletTransactionsFromIndex() uses address index to find
only transactions touching wallet keys (skips scanning every block)
- Follows spend chains to find related transactions
- Falls back to full scan if index unavailable
- Track index sync state with addressIndexBestChain/StartHeight in LevelDB

- Defer SecureMsgStart and ReacceptWalletTransactions to background thread
so GUI appears faster during startup
- Add shutdown checks in wallet scan/reaccept to prevent hanging on exit
- Smart wallet rescan: start from wallet birthday instead of genesis block
- Raise default dbcache from 25 to 128 MB for better performance
- Replace deprecated QDesktopServices with QStandardPaths (Qt5 compat)
- Enforce Qt5+ requirement in build system, remove -fpermissive flag
