Changes:

• Removed blank lines after pydantic imports in pr_verifier.py and issue_optimizer.py
• Refactored import statement in followup_issue_generator.py from from X import Y with getattr() to import X with direct attribute access

File	Description
scripts/langchain/pr_verifier.py	Removed blank line between third-party (pydantic) and first-party (scripts) imports
scripts/langchain/issue_optimizer.py	Removed blank line between third-party (pydantic) and first-party (scripts) imports
scripts/langchain/followup_issue_generator.py	Refactored langchain_core.messages import from from...import with getattr to import...as with direct access

According to PEP 8 import conventions, there should be a blank line between third-party imports (pydantic) and first-party imports (scripts). Removing this blank line violates PEP 8 import grouping standards. The ruff configuration in pyproject.toml includes isort (line 82: "I") which enforces these conventions and would likely flag this as an issue.

Suggested change

	from pydantic import BaseModel, ConfigDict, Field

This refactoring changes the error handling behavior. The original code used getattr with a default of None, which would gracefully handle the case where HumanMessage doesn't exist in the module. The new code directly accesses lc_messages.HumanMessage, which will raise an AttributeError (not caught by the ModuleNotFoundError handler) if HumanMessage doesn't exist. While unlikely in practice since HumanMessage is a core class, this represents a functional change in error handling that deviates from the defensive programming pattern used in the original code.

Suggested change

	human_message_cls = lc_messages.HumanMessage
	human_message_cls = getattr(lc_messages, "HumanMessage", None)
