v0.14.7 changes (hotfix)

Notable RPC/SDK changes

• [Execution] Mixed TX envelope decoding for eth_simulateV1 — accepts both direct legacy RLP list payloads and string-wrapped envelopes (EIP-2930, EIP-1559); fixes crash on legacy transactions
  • Ref: monad PR #2355
• [Execution] Throw on missing TX result — converts MONAD_ASSERT to MONAD_ASSERT_THROW in execute_block_transactions so RPC process fails gracefully instead of crashing
  • Ref: monad PR #2356

v0.14.6 changes (included in this release)

Highlights
