The module implements sophisticated evidence aggregation, quorum-based consensus, and automatic postponement of non-compliant supernodes.

Changes:

• Adds complete audit module infrastructure with keeper, types, and message handlers
• Implements deterministic window-based peer assignment and observation tracking
• Provides gRPC/REST query and transaction services with AutoCLI support

Review of changes since e4571ca. No new issues found. The latest commit fixes tests by adding build tags to separate supernode tests, refactoring test logic to use the auditQueryAssignedTargets helper, and adding a fallback for empty header hash in simulation/benchmarks.
