Fixed two critical issues preventing Homestead tests from passing: 1. DELEGATECALL hardfork guard - Added check to prevent DELEGATECALL (0xf4) execution before Homestead, as it was introduced by EIP-7 2.

…precompile Per EIP-4844 specification and Python reference implementation, when the point evaluation precompile receives invalid input (length != 192 bytes), it should raise KZGProofError BEFORE charging gas, resulting in 0 gas consumption rather than the full 50000 gas cost.
