Add safe mode for fetching untrusted URLs set_safe_mode(true) refuses anything but http and https, refuses hosts that resolve to loopback, private, link-local or reserved addresses, pins curl to the addresses that were checked (no DNS rebinding), and follows redirects one hop at a time so each is checked, dropping credentials when a redirect changes origin. Hosts or ranges can be allowed explicitly for development servers. Off by default. Adds a PHPUnit suite. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Only use HTTP/2 over TLS, and HTTP/1.1 for plain http Requesting CURL_HTTP_VERSION_2 makes curl send an h2c Upgrade request on plain http URLs, which some servers mishandle. PHP 7.3's built-in server drops the connection, which failed the curl tests on PHP 7.3. Use CURL_HTTP_VERSION_2TLS instead, curl's own default since 7.62: https still negotiates HTTP/2.
