feat: add initial project configuration and smoke tests

- Created pnpm workspace configuration to manage packages.
- Added a placeholder .gitkeep file in the scripts directory.
- Implemented a smoke test script to validate core API and web endpoints.
- Established TypeScript base configuration for consistent compilation settings.
- Introduced Turbo configuration for task management and build processes.

+# Davinci Platform — Developer Commands

+# Unified monorepo: packages/api (NestJS), packages/web (Next.js), packages/shared.
+#
+# Dev stack:  persistent data, ports 4300 (api) / 4000 (web) / 55434 (pg)
+# Test stack: ephemeral (always fresh DB), ports 4301 (api) / 4001 (web) / 45434 (pg)
+#
+# Usage:
+#   make help       Show all commands
+#   make dev        Start full dev stack
+#   make test       Full isolated smoke test
