Description

Make sure col() can be used on camelCase and other column names. May need to require wrapping in backticks or some other quoting character.

We should add an integration test for this.

This is most important for NodeJS, where camelCase fields are common.

Research direction
Review PR #3150 to understand the current col() implementation. Identify where column name quoting is handled in the NodeJS bindings. Write an integration test that uses camelCase column names and verifies col() returns correct results. If backtick quoting is needed, implement it and confirm other quoting characters still work.
