Turn on Query Profiler by Default to Sample Every Query Execution Thread Once a Second

Why it matters

This feature provides continuous lightweight profiling of query execution, helping users to monitor and diagnose query performance issues without manual activation. Enabling it by default increases observability and simplifies performance analysis.

How to use it

The query profiler runs automatically for every query execution thread at a sampling interval of one second. Users do not need to enable any settings to start benefiting from query profiling.
