The gojq review identified missing coverage for pathological filters interrupted during execution. Existing timeout handling needs no production changes or dependency upgrade.

• Resource-heavy filters: Add table-driven cases for billion-element range reduction and infinite tail recursion under caller deadlines and cancellation.
• Timeout contract: Cover the five-second default timeout, wrapped context error identity, and preservation of the caller’s context.

• Fixes [go-fan] Go Module Review: github.com/itchyny/gojq #15557

🟡 Changes recommended

The new error assertions conflict with the enabled testifylint require-error rule and would fail CI.
