Description

Updates the compression crate to include registry root handling.

Feature flag implementation:

• crates/compression/src/compress.rs: Added conditional compilation blocks to define CompressDb traits and implementations based on the "fault-proving" feature.
• crates/compression/src/ports.rs: Introduced the RegistryRootGetter trait for retrieving the registry root, with implementations conditioned on the "fault-proving" feature.

Registry root handling:

• crates/compression/src/compressed_block_payload/v1.rs: Modified CompressedBlockHeader to include a registry_root field and updated related methods to handle this field. [1] [2] [3]
• crates/compression/src/lib.rs: Updated VersionedCompressedBlock to include the registry_root when the "fault-proving" feature is enabled. [1] [2]

Tests:

• crates/compression/src/lib.rs: Enhanced tests to verify the inclusion of the registry_root in CompressedBlockHeader when the "fault-proving" feature is enabled. [1] [2] [3]

Additional changes:

• crates/fuel-core/src/graphql_api/da_compression.rs: Implemented the RegistryRootGetter trait for CompressDbTx to support registry root retrieval.
• crates/fuel-core/src/graphql_api/ports.rs: Added registry_root method to the DatabaseTransaction trait under the "fault-proving" feature.
• crates/fuel-core/src/graphql_api/storage.rs: Implemented the registry_root method to compute the root hash of various merkle trees in the temporal registry.

Note

we also add fault-proving feature to the integ tests, as well as ci target for it

Mostly looks good to me. Some thoughts and comments. Only blocker is the .unwrap_or(...default()) which at least should be unwrap_or_default, but I'd like to see an error there instead.

Looks good now, thanks!
