inspectDbCommand handles multiple distinct concerns (arg validation, filter scanning, operation-list q/u handling, mapReduce JS checks); split into smaller focused functions to reduce cognitive complexity.

✨ AI Reasoning
1. I identified a newly introduced method that analyzes raw DB command documents from the current execution context. 2. The method performs several distinct tasks: validate args, scan top-level command fields for filters, iterate list-style operation entries extracting 'q'/'u' keys, and delegate mapReduce handling. 3. These responsibilities are conceptually separate (filter detection vs. operation-list handling vs. JS map-reduce checks), increasing cognitive load. 4. A developer reading this method must mentally track multiple nested loops and different inspection rules, which reduces maintainability. 5. Breaking responsibilities into focused helpers would keep each unit easier to understand and test, improving long-term readability and correctness.
🔧 How do I fix it?
Break down long functions into smaller helper functions. Aim for functions under 60 lines with fewer than 10 local variables.

Comment restates the constant's purpose without adding rationale. Remove or replace with explanation why these fields matter for injection detection.

A constant lists MongoDB command fields that contain filters; the comment only rephrases that fact and provides no additional rationale or design intent beyond the constant name, so it likely adds maintenance burden.
