Update PNPM_SETUP.md to document aitbc-token pnpm migration

- Add aitbc-token project to overview section
- Document aitbc-token .npmrc configuration (engine-strict, no hoist)
- Add aitbc-token development commands (TypeScript-based)
- Update CI/CD Integration section to include package-tests.yml

 ## 📦 **Overview**
 
-The AITBC contracts directory uses **pnpm** as the package manager instead of npm. pnpm provides faster installations, better disk efficiency, and stricter dependency management.
+AITBC uses **pnpm** as the package manager for both smart contract projects:
+- `/opt/aitbc/contracts/` - Main Hardhat project (JavaScript-based)
+- `/opt/aitbc/packages/solidity/aitbc-token/` - Token contracts (TypeScript-based)
+
+pnpm provides faster installations, better disk efficiency, and stricter dependency management compared to npm.
 
 ## 📋 **Configuration Files**
 
 ### `.npmrc`
-The contracts directory includes a `.npmrc` file with the following settings:

 **Settings explained:**
 - **auto-install-peers=false**: Don't automatically install peer dependencies - requires explicit installation
 - **strict-peer-dependencies=true**: Fail if peer dependency requirements aren't met
 - **prefer-frozen-lockfile=true**: Use exact versions from lockfile (recommended for CI)
-- **shamefully-hoist=true**: Hoist dependencies to node_modules root (for compatibility with some tools)
+- **shamefully-hoist=true** (contracts only): Hoist dependencies to node_modules root for compatibility with older Hardhat
+- **engine-strict=true** (aitbc-token only): Enforce Node.js version requirement (>=24.14.0)
 
 ### `pnpm-lock.yaml`
 The lockfile is automatically generated and should be committed to version control. It ensures reproducible installs across environments.

 ## 🔄 **CI/CD Integration**
 
 All CI workflows have been updated to use pnpm:
-- `smart-contract-tests.yml`
+- `smart-contract-tests.yml` - Tests both contracts/ and aitbc-token/
-- `deploy-testnet.yml`
+- `package-tests.yml` - Tests aitbc-token/ package
-- `deploy-mainnet.yml`
+- `deploy-testnet.yml` - Testnet deployment
-- `contract-benchmarks.yml`
+- `deploy-mainnet.yml` - Mainnet deployment
-- `staking-tests.yml`
+- `contract-benchmarks.yml` - Performance benchmarks
+- `staking-tests.yml` - Staking contract tests
 
 Workflows automatically install pnpm if not available on the runner.
