Initial monorepo setup with npm workspaces and dual TypeScript configuration

- Set up npm workspaces for three packages: pi-tui, pi-agent, and pi (pods)
- Implemented dual TypeScript configuration:
  - Root tsconfig.json with path mappings for development and type checking
  - Package-specific tsconfig.build.json for clean production builds
- Configured lockstep versioning with sync script for inter-package dependencies
- Added comprehensive documentation for development and publishing workflows
- All packages at version 0.5.0 ready for npm publishing

+# Pi Monorepo
+
+A collection of tools for managing LLM deployments and building AI agents.
+
+## Packages
+
+- **[@mariozechner/pi-tui](packages/tui)** - Terminal UI library with differential rendering
+- **[@mariozechner/pi-agent](packages/agent)** - General-purpose agent with tool calling and session persistence
+- **[@mariozechner/pi](packages/pods)** - CLI for managing vLLM deployments on GPU pods
+
+## Development
+
+This is a monorepo using npm workspaces for package management and a dual TypeScript configuration for development and building.
+
+### Setup
+
+```bash
+# Install all dependencies
+npm install
+
+# Build all packages (required for production use)
+npm run build
+
+# Or run directly with tsx during development (no build needed)
+cd packages/pods && npx tsx src/cli.ts
+cd packages/agent && npx tsx src/cli.ts
+```
+
+### Common Commands
+
+```bash
+# Clean all build artifacts and tsconfig.tsbuildinfo files
+npm run clean
+
+# Build all packages in dependency order
+npm run build
+
+# Run biome checks and TypeScript type checking (no build required)
+npm run check
+
+# Run tests (if present)
+npm run test
+```
+
+### Package Dependencies
+
+The packages have the following dependency structure:
+
+`pi-tui` -> `pi-agent` -> `pi`
+
+### TypeScript Configuration
+
+The monorepo uses a dual TypeScript configuration approach:
+- **Root `tsconfig.json`**: Contains path mappings for all packages, used for type checking and development with `tsx`
+- **Package `tsconfig.build.json`**: Clean build configuration with `rootDir` and `outDir`, used for production builds
+
+This setup allows:
+- Type checking without building (`npm run check` works immediately)
+- Running source files directly with `tsx` during development
+- Clean, organized build outputs for publishing
+
+### Versioning
+
+All packages use **lockstep versioning** - they share the same version number:
+
+```bash
+# Bump patch version (0.5.0 -> 0.5.1)
+npm run version:patch
+
+# Bump minor version (0.5.0 -> 0.6.0)
+npm run version:minor
+
+# Bump major version (0.5.0 -> 1.0.0)
+npm run version:major
+```
+
+These commands automatically:
+1. Update all package versions
+2. Sync inter-package dependency versions
+3. Update package-lock.json
+
+### Publishing
+
+See [PUBLISHING.md](PUBLISHING.md) for the complete publishing workflow.
+
+Quick version:
+```bash
+# Dry run to see what would be published
+npm run publish:dry
+
+# Publish all packages to npm
+npm run publish:all
+```
