Add examples/quickstart/ with minimal copy-paste scripts that let new
users get a response from a local OmniRoute server in under a minute,
without needing to read the full docs first.
Files added:
- examples/quickstart/python_requests.py (requests library)
- examples/quickstart/nodejs_axios.js (axios)
- examples/quickstart/curl_terminal.sh (bash one-liner)
- examples/quickstart/php_curl.php (cURL extension)
- examples/quickstart/README.md (table + key-settings cheatsheet)
README.md: add one sub-line pointer to examples/quickstart/ below the
existing zero-config curl snippet, matching the surrounding <sub> style.
