fix: ensure lib is built before examples:build (#185)

Browse source 
* fix: ensure lib is built before examples:build

Add preexamples:build hook to automatically run `npm run build` before
`examples:build`. This ensures examples always type-check against the
latest library code, catching breaking changes during development.

🤖 Generated with [Claude Code](https://claude.com/claude-code)

Co-Authored-By: Claude <noreply@anthropic.com>

* feat: add version consistency check for examples

Add scripts/check-versions.mjs to verify that example package.json files
reference the correct version of @modelcontextprotocol/ext-apps.

- Allows "../.." (local dev) or "^{root-version}" as valid dependencies
- Runs in CI before npm install to catch mismatches early
- Available locally via `npm run check:versions`
