/**
 * No-Telemetry Build Plugin for OpenClaude
 *
 * Replaces all analytics, telemetry, and phone-home modules with no-op stubs
 * at compile time. Zero runtime cost, zero network calls to Anthropic.
 *
 * This file is NOT tracked upstream — merge conflicts are impossible.
 * Only build.ts needs a one-line import + one-line array entry.
 *
 * Kills:
 *   - GrowthBook remote feature flags (api.anthropic.com)
 *   - Datadog event intake
 *   - 1P event logging (api.anthropic.com/api/event_logging/batch)
 *   - BigQuery metrics exporter (api.anthropic.com/api/claude_code/metrics)
 *   - Perfetto / OpenTelemetry session tracing
 *   - Auto-updater (storage.googleapis.com, npm registry)
 *   - Plugin fetch telemetry
 *   - Transcript / feedback sharing
