/**
 * Monorepo Support Validation Tests
 *
 * Architecture after deduplication:
 * - Monorepo context logic lives ONLY in context-logic.js
 * - workflow.xml (src) uses {{monorepo_context_logic}} placeholder → injected at install time
 * - Individual source workflow files do NOT have inline checks (that's the deduplication!)
 * - Only code-review/instructions.xml, dev-story/instructions.xml, create-story/instructions.xml
 *   and advanced-elicitation/workflow.xml are XML workflows checked; XML workflows that go through
 *   workflow.xml no longer need inline checks.
 *
 * Verifies:
 * 1. The set-project workflow is correctly registered.
 * 2. No source workflow file has a stale inline "Monorepo Context Check" block.
 * 3. Only the canonical SINGLE source (context-logic.js) defines the check.
 * 4. set-project implementation still manages .current_project.
