Summary

• Return PostgreSQL's bigint range error for INT64_MIN / -1 in agtype integer division.
• Add a Cypher regression case for the reported expression.

Evidence

• Reproduces the crash described in Integer division by -1 on INT64_MIN raises a misclassified floating-point exception (22P01) instead of bigint out of range #2590: RETURN (-9223372036854775807 - 1) / -1 reaches unchecked signed integer division.
• PostgreSQL reports bigint out of range for the same operands.

Merge Danger

• Low: the guard affects only the overflowing signed 64-bit integer division pair; other numeric paths are unchanged.

Closes #2590

I corrected the expected regression output in ce6da4f to match the bigint-overflow error shown by the failing CI diff. git diff --check passes; I have not run the PostgreSQL regression suite locally. Could you approve or rerun the regression workflow on this head so we can confirm the output is aligned?
