[Epic 1] Monorepo foundation with uv workspaces

[ulises-jeremias]

Summary

Bootstrap a virtual uv workspace root with packages/*, lockfile, Python pin, LICENSE, gitignore, editorconfig, bootstrap README, AGENTS.md, and VS Code settings.

CNA mapping

package.json workspaces + turbo.json + root scripts → pyproject.toml [tool.uv.workspace] + uv.lock + uv run.

Why

All packages depend on a shared workspace; must exist before core/CLI.
