Initialize Varbase AI Context recipe

Problem/Motivation

Every new Varbase site starts with zero AI context. The ten Varbase AI agents (Page Builder, Template Builder, Title Generation, Orchestrator, Field Agent, Taxonomy Agent, Editor Assistant, etc.) fall back to generic
Drupal knowledge, they don't know Varbase brand terminology, content types, or editorial workflow. Site builders must hand-create every context item via Admin → AI → Context.

Proposed resolution

Initialize a varbase_ai_context recipe that installs ai_context and pre-populates starter context items:

• Varbase Brand & Identity Guidelines terminology, tone, content rules.
• Varbase AI Editorial Rules content types (Blog post, Utility page, Canvas page, Media, Webform submissions, Taxonomy), writing standards, moderation workflow, SEO, forbidden content.
• AI Safety Guardrails Varbase hard stops, scope limits, disclosure, incident reporting.
