Description
Add malicious behavior simulation for BEP-657 blob chaos testing. This enables integration tests to validate blob transaction handling under fault injection scenarios.
Rationale
tell us why we need these changes...
Example
Allow packing blob transactions even when block number N % 5 != 0
Simulates a malicious validator attempting to include blobs in non-eligible blocks
Corrupt blob sidecar data during P2P broadcast
XORs the first byte of each blob to simulate data corruption
Drop blob sidecars entirely during P2P broadcast
Simulates missing blob data in P2P propagation
New RPC methods under miner namespace:
miner_setForceBlobOnNonEligible(bool) - Toggle forcing blobs on non-eligible blocks
miner_setCorruptBlobSidecar(bool) - Toggle blob sidecar corruption
miner_setDropBlobSidecar(bool) - Toggle blob sidecar dropping
All methods return the current MBConfig state.
