Scripts like GTM and GA4 are often blocked by ad blockers and privacy extensions when loaded from third-party domains, leading to data loss. Third-party cookie deprecation further limits tracking durability. This change proxies GTM scripts and analytics beacons through the Trusted Server, establishing a first-party context. It automatically rewrites HTML tags and script content to point to local proxy endpoints, bypassing blockers and extending cookie life. Includes: Proxy endpoints for gtm.js and /collect Content rewriting for redirecting internal GTM calls Configuration and integration tests Resolves: #224
Adds comprehensive tests for: - GTM configuration parsing and default values - HTML processor pipeline integration - Response body rewriting logic
