gtm-implementation

Implements complete GTM tracking including dataLayer events in code and GTM configuration via API. Use when users need to "implement GTM tracking", "add dataLayer events", "create GTM variables and tags", "set up CTA tracking", "implement event tracking", or want to execute a tracking plan. Handles both code implementation (dataLayer.push) and GTM container configuration (variables/triggers/tags) automatically via API. Supports incremental updates and framework-specific patterns (React, Next.js, Vue, etc.).
