feat: Add automated package-lock.json sync tooling

✨ New Features:
- sync-lockfile.sh: Auto-sync lock file with package.json changes
- install-hooks.sh: Install git pre-commit hooks
- ci-sync-lockfile.sh: CI/CD auto-fix for lock file issues
- Pre-commit hook: Automatically runs on git commit
- validate-lockfile.yml: GitHub Actions workflow for validation

📚 Documentation:
- CONTRIBUTING.md: Complete contribution guide
- scripts/README.md: Automation scripts documentation

🎯 Benefits:
- Prevents "lock file out of sync" CI/CD failures
- Automatic staging of lock file changes
- Zero manual intervention needed
- Works with any workflow (hooks, manual, CI/CD)

🔧 Usage:
1. Install hooks: ./scripts/install-hooks.sh
2. Add dependencies normally
3. Commit - hook auto-syncs lock file
4. CI validates automatically

Resolves the recurring package-lock.json sync issues.

+# Contributing to RuVector
+
+Thank you for your interest in contributing to RuVector!
+
+## Development Setup
+
+### 1. Clone the Repository
+
+```bash
+git clone https://github.com/ruvnet/ruvector.git
+cd ruvector
+```
+
+### 2. Install Dependencies
+
+```bash
+cd npm
+npm install
+```
+
+### 3. Install Git Hooks (Recommended)
+
+We provide git hooks that automatically keep `package-lock.json` in sync:
+
+```bash
+./scripts/install-hooks.sh
+```
+
+This will:
+- Automatically run `npm install` when you modify `package.json`
+- Stage the updated `package-lock.json` automatically
+- Prevent CI/CD failures due to lock file mismatches
+
+## Package Management
+
+### Adding Dependencies
+
+When adding new dependencies to any package:
+
+```bash
+cd npm/packages/<package-name>
+npm install <dependency>
+```
+
+**Important**: Always commit the updated `package-lock.json` with your changes!
+
+### Manual Lock File Sync
+
+If you forget to sync the lock file, you can use our helper script:
+
+```bash
+./scripts/sync-lockfile.sh
+```
+
+## Common Issues
+
+### CI/CD Fails with "Lock file out of sync"
+
+**Problem**: `npm ci` fails with:
+```
+npm error `npm ci` can only install packages when your package.json and package-lock.json are in sync
+```
+
+**Solution**:
+```bash
+cd npm
+npm install
+git add package-lock.json
+git commit -m "fix: Sync package-lock.json"
+git push
+```
+
+Or use the automated script:
+```bash
+./scripts/sync-lockfile.sh
+```
+
+### Pre-commit Hook Not Working
+
+If the git hook isn't triggering:
+
+```bash
+# Reinstall hooks
+./scripts/install-hooks.sh
+
+# Verify hook is executable
+ls -la .git/hooks/pre-commit
+```
+
+## Development Workflow
+
+1. **Create a feature branch**
+   ```bash
+   git checkout -b feat/your-feature-name
+   ```
+
+2. **Make your changes**
+   - Write code in the appropriate package
+   - Add tests for new features
+   - Update documentation
+
+3. **Build and test**
+   ```bash
+   cd npm
+   npm run build
+   npm test
+   ```
+
+4. **Commit your changes**
+   ```bash
+   git add .
+   git commit -m "feat: Your descriptive commit message"
+   ```
+
+   The pre-commit hook will automatically sync the lock file if needed.
+
+5. **Push and create PR**
+   ```bash
+   git push origin feat/your-feature-name
+   ```

-# Ruvector Scripts
+# RuVector Automation Scripts
 
-Automation scripts for development, publishing, and maintenance.
+This directory contains automation scripts to streamline development and prevent common issues.
 
-## Publishing Scripts
+## 📜 Available Scripts
 
-### publish-crates.sh
+### 🔄 sync-lockfile.sh
+Automatically syncs `package-lock.json` with `package.json` changes.
 
-Automated script to publish all Ruvector crates to crates.io in the correct dependency order.
+**Usage:** `./scripts/sync-lockfile.sh`
 
-**Prerequisites**:
+### 🪝 install-hooks.sh
-- Rust and Cargo installed
+Installs git hooks for automatic lock file management.
-- `CRATES_API_KEY` in `.env` file (never hardcoded!)
-- All crates build successfully
-- All tests pass
 
-**Usage**:
+**Usage:** `./scripts/install-hooks.sh`
 
-```bash
+### 🤖 ci-sync-lockfile.sh
-# Make executable
+CI/CD script for automatic lock file fixing.
-chmod +x scripts/publish-crates.sh
 
-# Run publishing
+**Usage:** `./scripts/ci-sync-lockfile.sh`
-./scripts/publish-crates.sh
-```
 
-**What it does**:
+## 🚀 Quick Start
-1. Loads `CRATES_API_KEY` from `.env` (secure, not hardcoded)
-2. Authenticates with crates.io
-3. Publishes crates in dependency order:
-   - Phase 1: `ruvector-core`, `router-core` (base crates)
-   - Phase 2: `ruvector-node`, `ruvector-wasm`, `ruvector-cli`, `ruvector-bench`
-   - Phase 3: `router-cli`, `router-ffi`, `router-wasm`
-4. Waits between publishes for crates.io indexing
-5. Reports success/failure summary
 
-**Safety Features**:
+1. **Install git hooks** (recommended):
-- ✅ Reads credentials from `.env` (gitignored)
+   ```bash
-- ✅ Never hardcodes API keys
+   ./scripts/install-hooks.sh
-- ✅ Verifies packages before publishing
+   ```
-- ✅ Skips already published versions
-- ✅ Provides detailed error messages
-- ✅ Waits for crates.io indexing
 
-## Security
+2. **Test the hook**:
+   ```bash
+   cd npm/packages/ruvector
+   npm install chalk
+   git add package.json
+   git commit -m "test: Add chalk dependency"
+   # Hook automatically updates lock file
+   ```
 
-⚠️ **Important**: This directory may contain scripts that use sensitive credentials.
+See [CONTRIBUTING.md](../docs/CONTRIBUTING.md) for full documentation.
-
-**Always**:
-- Store credentials in `.env` (gitignored)
-- Use `.env.example` for templates
-- Never hardcode API keys in scripts
-- Review scripts before execution
-
-See [SECURITY.md](../docs/development/SECURITY.md) for security best practices.
-
-## Development Scripts
-
-*More scripts will be added here as the project grows*
-
-Potential additions:
-- `test-all.sh` - Run all tests across crates
-- `bench-all.sh` - Run all benchmarks
-- `check-format.sh` - Verify code formatting
-- `update-docs.sh` - Update documentation
-
-## Contributing
-
-When adding new scripts:
-
-1. **Document thoroughly** - Add comments and usage examples
-2. **Use .env for secrets** - Never hardcode credentials
-3. **Make executable** - `chmod +x scripts/your-script.sh`
-4. **Add to this README** - Document purpose and usage
-5. **Test thoroughly** - Verify on clean checkout
-6. **Error handling** - Exit on errors (`set -e`)
-7. **Colored output** - Use colors for clarity
