Milestone 0: import zappier billing, Verae middleware, and Zapier research

Compose-ready workspace: packages/zappier (rate card, portal, Stripe),
packages/verae-zapier-middleware (timestamp + NATS), packages/verae-zapier
(CLI app), vendor/zapier-platform, and research/zapier vendor corpus.

Gate 0 structure checks pass. Product code and research are not yet wired.

+# Command Quick Reference
+
+## Root-Level Commands (run from repository root)
+
+### Installation & Setup
+```bash
+pnpm install           # Install all dependencies
+```
+
+### Testing
+```bash
+pnpm test              # Run all tests (all packages + schema-to-ts)
+pnpm smoke-test        # Run smoke tests (cli, core, schema only)
+pnpm validate          # Full validation (test + smoke-test + lint)
+```
+
+### Code Quality
+```bash
+pnpm lint              # Lint all packages
+pnpm lint:fix          # Fix linting issues
+```
+
+### Build & Release
+```bash
+pnpm generate-types    # Generate TypeScript declarations
+pnpm bump     # Bump versions across packages
+```
+
+## Package-Specific Commands (cd into package first)
+
+### CLI (`packages/cli/`)
+```bash
+pnpm test              # Unit tests
+pnpm smoke-test        # Smoke tests  
+pnpm validate          # test + smoke-test + lint
+```
+
+### Core (`packages/core/`)
+```bash
+pnpm main-tests        # Unit tests only
+pnpm type-tests        # TypeScript definition tests
+pnpm test              # main-tests + solo test + type-tests
+pnpm integration-test  # Integration tests
+pnpm smoke-test        # Smoke tests
+pnpm validate          # Full validation
+```
+
+### Schema (`packages/schema/`)
+```bash
+pnpm test              # Unit tests
+pnpm smoke-test        # Smoke tests
+pnpm validate          # test + smoke-test + lint
+```
+
+### Schema-to-ts (`schema-to-ts/`)
+```bash
+pnpm test              # Uses vitest (not mocha)
+```
+
+## Development Workflow Tips
+
+- **Individual package testing**: Always `cd` into package directory first
+- **Full validation**: Use `pnpm validate` at root for comprehensive checking
+- **Focused testing**: Use `.only` in Mocha for specific test cases
+- **TypeScript types**: Generated automatically via husky precommit hooks

+## Package Linking for Integration Development
+
+When developing integrations, you may want to link to your local development versions of core and schema instead of the published npm packages.
+
+### Setup Links
+```bash
+# Register the packages for linking
+cd packages/core && pnpm link
+cd packages/schema && pnpm link
+```
+
+### Use in Integration Project
+```bash
+# In your integration project directory
+pnpm link zapier-platform-core
+pnpm link zapier-platform-schema
+```
+
+### Verify Linking
+```bash
+# Check that packages are symlinked
+ls -hl node_modules/zapier-platform-*
+# Should show: node_modules/zapier-platform-core -> .../pnpm/global/5/node_modules/zapier-platform-core
+```
+
+### Unlink
+```bash
+# Return to npm packages
+pnpm unlink zapier-platform-core
+pnpm unlink zapier-platform-schema
+```
