 * Context-aware logger for scoped logging within a request or execution context.
 *
 * Buffers log messages and associates them with a specific context (like an HTTP request).
 * Supports log level filtering, buffering, and automatic flushing when the context ends.
 *
 * ### Usage
 *
 * ```typescript
 * import {ContextLogger} from "@tsed/di";
 *
 * const logger = new ContextLogger({id: "req-123"});
 *
 * logger.info("Processing request");
 * logger.debug("Debug info");
 *
 * await logger.flush(); // Write buffered logs
 * ```
