fix: resolve lint error blocking sync workflow

[stranske]

Problem

The sync workflow (maint-68-sync-consumer-repos.yml) has been failing because scripts/langchain/issue_optimizer.py has a line exceeding the 100 character limit.

Solution

Split the long f-string on lines 633 and 823 into multiple lines.

Evidence

Checking scripts/langchain/issue_optimizer.py...
E501 Line too long (126 > 100)
   --> scripts/langchain/issue_optimizer.py:633:101

This fix unblocks the sync workflow so consumer repos receive the latest updates.

Pull request overview

This PR fixes line length lint errors (E501) in issue_optimizer.py that were blocking the sync workflow. The linter detected lines exceeding the 100-character limit at lines 633 and 823.

Changes:

• Extract error type name into err_type variable before print statements
• Split long f-strings across multiple lines to comply with line length limit

For consistency, consider whether extracting err_type here is the best approach. Lines 646 and 838 have similar error handling patterns but use type(e).__name__ inline without extraction. Either all four locations should extract the error type into a variable, or all should use inline extraction. Alternatively, if line length is the only concern, the f-string could be split without introducing the intermediate variable.
