Bump reth-firehose to op-rs-aef8d3e-fh-1, which emits the genesis block (with full alloc) via a new emit_genesis_block_on_empty_chain helper and drops the block-1 "genesis marker" hack. Wire the emission from on_node_started (genesis only exists in the DB after launch init) and trace block 1 through the normal path. Note: op-rs-aef8d3e-fh-1 must be pushed to streamingfast/reth before this builds from the remote. Branch already failed to compile before this change (reth-optimism-primitives Compact errors from the in-progress v2.4.2 adaptation), so this commit is compile-verified only insofar as it mirrors the pattern proven on streamingfast/reth firehose/2.x.

op-rs-aef8d3e-fh-1(streamingfast/reth#25), which emits the genesis block (with full alloc) via the newemit_genesis_block_on_empty_chainhelper and drops the block-1 "genesis marker" hack.

op-rethbin builds against the tag) and smoke-tested: fireeth-wrapped standalone op-reth on an empty chain emitsFIRE BLOCK 0with the full L2 genesis alloc (2081 code changes / 2085 storage changes / 266 balance changes), zero parent, correct genesis hash; re-emits only while the head is still at genesis.Note:
