Describe the feature

1. Merge --features risc0 with -- --proof-gen flags
2. in main.rs, Claude modified topic by adding mut and cloned forkhttps://github.com/DimitriosMitsios/ream/blob/1f85daa2154c312011f4daaebd0283007771c4bc/bin/ream/src/main.rs#L183C1-L203C1
3. IMPORTANT In message.rs we modified LeanGossipSubMessage removing PartialEq, Eq. Is this acceptable for the Ream team?

   ream/crates/networking/p2p/src/gossipsub/lean/message.rs

   Line 12 in 1f85daa

   #[cfg(not(feature = "risc0"))]

4. We used bincode to deserialise block_proof in contrast to ssz ethereum library that was used for the rest of gossipsub messages, is it acceptable?

   ream/crates/networking/p2p/src/gossipsub/lean/message.rs

   Line 34 in 1f85daa

   // Use bincode for BlockProof since it contains risc0 Receipt

5. Check Cargo.toml files especially the one include ream-chain-lean with optional = true
