Description

I m using the latest version v4.0.6, before this I was using v4.0.4, I get the following stacktrace after entering "+", "(", "*)" as the filter expression.

SyntaxError: Invalid regular expression: /^[\s\S]*?+$/: Nothing to repeat

I have used to sort out this by "condition: uiGridConstants.filter.CONTAINS", it works on grids having server side filtering while its not working for other grids

Research direction
The error originates in the guessCondition function in ui grid.js around line 9731, where user input is directly used to construct a regex without escaping special characters. The fix involves sanitizing the filter term by escaping regex meta characters (e.g., +, *, (, )) before building the pattern. Adding a utility function and testing with various inputs will resolve the issue.
