Merge rc1 into feature/economic-system-and-rewards with conflict resolution

[Copilot]

Merge rc1 production-hardened code into feature branch, resolving 7 file conflicts while preserving economic system features.

Conflicts Resolved

• blockchain.rs - Kept VRF chaining implementation over simpler hash+height approach; retained tracing::error! over eprintln!
• dht.rs, network.rs, rpc.rs - Kept feature branch production improvements
• state/lib.rs - Preserved credit_account method for block reward minting
• battle_circuit.rs, state_circuit.rs - Kept detailed doc comments and error handling improvements

Key Decisions

Conflict	Resolution
VRF input generation	Proper chaining from previous block's VRF output
Logging	tracing::error! for structured production logging
Transaction lookup	Kept tx_index for O(1) hash lookups
Block rewards	Preserved credit_account in StateManager

Files Added

• todo_now.md - RC1 readiness audit from rc1 branch
