LogLevel
A platform-independent log level, carrying its OTLP severity mapping.
Each level maps to the base of its OTLP SeverityNumber range (TRACE→1, DEBUG→5, INFO→9, WARN→13, ERROR→17) and a human-readable severity text. The capture core copies both onto each LogRecord so the buffer is OTLP-shaped from the moment of capture.
Levels are declared least-to-most severe; ordinal is therefore a valid severity comparison and is what CaptureConfig.minLevel filters against.
