Inserts a value into a SlidingStats and conditionally logs the current stats using tracing.

This macro inserts the given $value into the $stats collector only if tracing is enabled for the given $target and $level. The log will be emiited only if enough time has passed since the last logged output (as tracked by the internal last_log timestamp).

The macro respects throttling: stats will not be logged more frequently than either the explicitly provided log_interval or the stats’ retention period (if no interval is given).

Note that:

• Logging is skipped unless tracing::enabled! returns true for the target and level.
• All entries older than the retention period will be logged and pruned,
• The newly inserted value may not be included in the logged statistics output (it is inserted after the log decision).
