PR Summary

Low Risk
Changes are limited to test/data-generation scaffolding and dependency wiring; core runtime logic isn’t modified. Main risk is build/test fallout from the new starknet_committer dev-dependency and the refactor leaving placeholder unimplemented!() paths for future work.

Overview
Refactors the blob regression test data generation from a set of free functions into a BlobFactory/BlockData structure that will own chain info, state, and per-block artifacts, with finalize() producing blobs plus a preconfirmed block.

Adds starknet_committer (and related storage types) as a new dev-dependency and updates the test to derive chain_info from the factory instead of a global static; most generation logic remains as TODO/unimplemented placeholders.

    fn current_state_roots(&self) -> StateRoots {
        self.blocks.last().map(|block| block.state_roots).unwrap_or_default()

unrelated to this PR, but consider adding this constant to StateRoots

Suggestion:

self.blocks.last().map(|block| block.state_roots).unwrap_or(StateRoots::ROOTS_OF_EMPTY_STATE)

Lets use the same terminology

Suggestion:

    #[expect(dead_code)]
    fn last_finalized_block_hash(&self) -> BlockHash {
        self.blocks.last().map(|block| block.block_hash).unwrap_or(BlockHash::GENESIS_PARENT_HASH)
