The `dintel-gtm-toolkit` Python scripts (analyze_container.py,
diff_versions.py, validate_tags.py, find_unused.py) have been
replaced by the DTM Agent skill set, which operates on live
containers via the GTM API instead of exported JSON.
- .claude/commands/gtm-guardian.md: rewrite as a deprecation
pointer with old→new mapping for every script/phase
(Phase 6 → /dtm-audit + /dtm-debug, Phase 7 → /dtm-taxonomy +
/dtm-lookup, etc.).
- custom-skills/62-gtm-validator/code/references/phase6-audit.md:
replace "D.intelligence GTM Toolkit Integration" section with
DTM Agent skill map, live-container workflow, and dtm CLI
examples; update objective #4.
