Documentation:
- Corrected typographical errors in various files to improve readability
and understanding. Changes include spelling corrections in the Makefile,
block/header-sync.md, specs/lazy-adr/adr-009-state-fraud-proofs.md, and
state/block-executor.md. These changes do not impact the functionality
of the system but enhance the clarity of the documentation and code
comments.

+All three types of nodes (sequencer, full, and light) run the header sync service to maintain the canonical view of the rollup chain (with respect to the P2P network).
 
 The header sync service inherits the `ConnectionGater` from the node's P2P client which enables blocking and allowing peers as needed by specifying the `P2PConfig.BlockedPeers` and `P2PConfig.AllowedPeers`.
