feat: add version management scripts and CI check

- Added update-version.js script to automate version bumps across all packages
- Added check-version-consistency.js script to verify version consistency
- Integrated version check into CI workflow
- Scripts check package.json versions AND package-lock.json sync
- Added npm scripts: `npm run update-version` and `npm run check-version`
- Added documentation in scripts/README.md

This ensures version consistency across the monorepo and prevents
accidental version mismatches or outdated lock files.

+# Version Management Scripts
+
+This directory contains scripts for managing version consistency across the monorepo.
+
+## Scripts
+
+### update-version.js
+
+Updates the version across all package.json files in the monorepo and updates package-lock.json.
+
+**Usage:**
+```bash
+npm run update-version <new-version>
+# Example:
+npm run update-version 0.14.3
+```
+
+This script will:
+1. Update the version in all package.json files (root, client, server, cli)
+2. Update workspace dependencies in the root package.json
+3. Run `npm install` to update package-lock.json
+4. Provide next steps for committing and tagging
+
+### check-version-consistency.js
+
+Checks that all packages have consistent versions and that package-lock.json is up to date.
+
+**Usage:**
+```bash
+npm run check-version
+```
+
+This script checks:
+1. All package.json files have the same version
+2. Workspace dependencies in root package.json match the current version
+3. package-lock.json version matches package.json
+4. Workspace packages in package-lock.json have the correct versions
+
+This check runs automatically in CI on every PR and push to main.
+
+## CI Integration
+
+The version consistency check is integrated into the GitHub Actions workflow (`.github/workflows/main.yml`) and will fail the build if:
+- Package versions are inconsistent
+- package-lock.json is out of sync
+
+## Common Workflows
+
+### Bumping version for a release:
+```bash
+# Update to new version
+npm run update-version 0.15.0
+
+# Verify everything is correct
+npm run check-version
+
+# Commit the changes
+git add -A
+git commit -m "chore: bump version to 0.15.0"
+
+# Create a tag
+git tag 0.15.0
+
+# Push changes and tag
+git push && git push --tags
+```
