/**
 * Structured debug logger for the OpenViking Agent Plugins 1.0 package.
 *
 * VENDORED (adapted) from examples/claude-code-memory-plugin/scripts/debug-log.mjs —
 * keep in sync with that file.
 *
 * Activation: OPENVIKING_DEBUG=1 env var.
 * Log path:   OPENVIKING_DEBUG_LOG env var OR ~/.openviking/logs/agent-plugins.log.
 * Format:     JSON Lines — { ts, hook, stage, data } | { ts, hook, stage, error }.
 *
 * When inactive, log() and logError() are zero-cost no-ops.
