/**
 * Prerun hook that enables debug logging when --debug flag is present.
 *
 * This hook runs after command resolution but before run() execution. Since
 * oclif has already instantiated the command and will execute the original
 * run() method, we enable the DebugLogger globally so that SERVICE and
 * ADAPTER layers produce debug output.
 *
 * Architecture:
 * - Checks for --debug flag in argv
 * - Enables DebugLogger globally
 * - SERVICE and ADAPTER layers check DebugLogger.isEnabled()
 * - Zero overhead when --debug flag is not present
 *
 * Note: CLI-layer command logging (flags, timing) would require a base command
 * class or command-level changes. This implementation focuses on enabling
 * SERVICE → ADAPTER debug output which is the primary use case.
