Pull request overview

Adds a cached ProfilingData instance inside Profiler to avoid repeatedly constructing ProfilingData on each disable() call—intended to help performance in long-running PHP processes (e.g., Laravel Octane).

Changes:

• Introduce Profiler::$profilingData and a private getProfilingData() lazy-initializer to reuse a single ProfilingData instance.
• Update Profiler::disable() to use the cached ProfilingData instance.
• Add a unit test asserting getProfilingData() returns the same cached instance across calls.
