Krystie fb07d50235 feat: compact blocks, column families, fork detector, cross-network discovery, SAM v3, configurable peers
BIP152 Compact Blocks (main.cpp, net.cpp, protocol.h):
- SipHash-2-4 short IDs (48-bit) for transaction identification
- Compact block relay with mempool reconstruction
- Merkle root verification before acceptance
- Graceful fallback to full block on any mismatch
- Collision detection for ambiguous short IDs

RocksDB Column Families (txdb-rocksdb.cpp/h):
- 5 CFs: default, blockindex, txindex, utxo, addrindex
- Per-CF tuning: UTXO optimized for point lookups, addrindex for scans
- Backward-compatible: falls back to default CF for pre-migration data
- Prefix-based routing in ReadRaw/WriteRaw/EraseRaw/ExistsRaw

Fork Detector (main.cpp, net.cpp, net.h):
- Background thread checks local tip vs peer median every 60s post-IBD
- Alerts on divergence > forkthreshold (default 5 blocks)
- Optional auto-rebuild trigger on severe divergence

Cross-Network Tor↔I2P Discovery (net.cpp, init.cpp):
- I2P seed addresses loaded into addrman alongside onion seeds
- Address relay bridges .onion and .b32.i2p between networks
- IsI2PAddr/IsOnionAddr helpers for network-type detection

Configurable Outbound Connections (net.cpp, init.cpp):
- -maxoutboundconnections flag (range 4-32, default 8)

Mempool Fee-Priority Boost (miner.cpp):
- 2x fee weight in PoS block assembly for higher staking rewards

SAM v3 Direct Streaming (i2p/i2p_embedded.cpp/h):
- CI2PSamSocket class with full SAM v3 protocol
- SESSION CREATE + STREAM CONNECT handshake
- Factory method on CI2PEmbedded for native I2P connections
- SAM bridge readiness check in bootstrap loop
