Template Library Storage - COMPLETE ✅

Completed 2026-02-08:

1. Docker Template Seeding Fix

   • ✅ Dockerfile now copies examples/templates/ into /app/templates during build
   • ✅ FindTemplatesDirectory() already checks Path.Combine(baseDir, "templates") — resolves immediately in Docker

2. IDocumentStore Migration

   • ✅ BlueprintTemplateService migrated from Dictionary<string, BlueprintTemplate> to IDocumentStore<BlueprintTemplate, string>
   • ✅ Thread-safe via InMemoryDocumentStore (uses ConcurrentDictionary internally)
   • ✅ Swappable to MongoDB with a single DI registration change
   • ✅ Consistent with Blueprint Service's in-memory storage pattern (line 36: "later: replace with EF Core + PostgreSQL")

Test Results: 224 tests passing (all unchanged)
