Triangles v5.0.0.0 - Chain revival with Tor v3, messaging, and seed nodes

Browse Source 
- Revived frozen chain (Dec 2022) with two live seed nodes
- Added Tor v3 onion hidden service support (Ed25519)
- Wired seeder message handlers (seeder/getseederlist/seederlist)
- Hardcoded onion seeds and clearnet IP seeds for DNS2/DNS3
- Fixed bind address (0.0.0.0) so nodes accept external connections
- Added boost_chrono to makefile.unix for modern Boost
- Fixed LoadExternalBlockFile block-skip bug for faster imports
- Import-only optimizations for chain replay (checkpoint-gated)
- Added sort_blocks.c tool for blockchain data recovery
- Comprehensive README with build/run/messaging/Tor instructions
- Chain revival status document for project coordination
