v0.9.6: InfoNet hashchain, Wormhole gate encryption, mesh reputation, 16 community contributors

Gate messages now propagate via the Infonet hashchain as encrypted blobs — every node syncs them
through normal chain sync while only Gate members with MLS keys can decrypt. Added mesh reputation
system, peer push workers, voluntary Wormhole opt-in for node participation, fork recovery,
killwormhole scripts, obfuscated terminology, and hardened the self-updater to protect encryption
keys and chain state during updates.

New features: Shodan search, train tracking, Sentinel Hub imagery, 8 new intelligence layers,
CCTV expansion to 11,000+ cameras across 6 countries, Mesh Terminal CLI, prediction markets,
desktop-shell scaffold, and comprehensive mesh test suite (215 frontend + backend tests passing).
