- Introduced logging for highly dynamic endpoints by tracking ETag history for each endpoint.
- Implemented a mechanism to limit the number of tracked ETags and log when all tracked ETags are unique.
- Updated documentation to reflect the new logging feature and its implications for performance optimization.

- Integrated `config/etag.php` for dynamic configuration of ETag functionality.
- Added `enabled` and `log_dynamic_endpoints` flags to control feature behavior.

This update improves flexibility and allows disabling ETag processing entirely when `enabled` is set to false.

- Added custom Trend metrics to measure and compare durations of 200 OK and 304 Not Modified responses
- Validates that 304 responses are faster using If-None-Match header
- Improved test clarity by focusing on ETag performance under load

- Implemented tracking of ETag values for specified endpoints
- Added logic to identify dynamic endpoints when ETag history shows diff values
