release: v3.18.2 - Steinberger Practitioner Insight

Add Peter Steinberger (PSPDFKit Founder, Moltbot Creator) to Practitioner
Insights with model-agnostic workflow patterns.

Changes:
- Add Steinberger entry in guide/ai-ecosystem.md (stream monitoring,
  multi-project juggling, fresh context validation, iterative exploration)
- Complete evaluation in docs/resource-evaluations/steinberger-inference-speed.md
  (score 3/5, fact-checked GPT-5.2, validated credentials)
- Update docs/resource-evaluations/README.md (15→16 evaluations)
- Add practitioner_steinberger references in machine-readable/reference.yaml
- Version bump 3.18.1 → 3.18.2 (VERSION + sync all docs)
- Update CHANGELOG.md with detailed v3.18.2 entry
- Update README.md evaluations count (22→25)

Scope: Model-agnostic patterns only, zero model comparisons.
