feat: assert chain segment in range sync

[twoeths]

Motivation

• we only valid chain segment in processBlocks(), we should have validated earlier right after we download it

Description

• enhance assertLinearChainSegment() with an optional parentBlock
• call it right after we download a range segment
• add logs penalize peer

Code Review

This pull request implements linearity validation for block segments during range sync by updating the assertLinearChainSegment utility to handle null parent blocks and integrating it into the RangeSync process. It also introduces new error codes for invalid chain segments and includes comprehensive unit tests for the updated validation logic. Feedback was provided regarding the performance of logging operations, suggesting that expensive data transformations for verbose logs should be wrapped in a log-level check to avoid unnecessary overhead in production.
