64-64: Consider calling out the Lotus name here.

Operators migrating from Lotus may look for LOTUS_GENESIS_NETWORK_VERSION, so a brief note that this is Forest’s equivalent would make the docs a bit more discoverable.

✏️ Suggested wording

-| `FOREST_GENESIS_NETWORK_VERSION`                          | non-negative integer            | empty                                          | 25                                                            | Override the genesis network version (devnet only)                                                                    |
+| `FOREST_GENESIS_NETWORK_VERSION`                          | non-negative integer            | empty                                          | 25                                                            | Override the genesis network version (devnet only). Forest-specific equivalent of Lotus's `LOTUS_GENESIS_NETWORK_VERSION` |
