⚠ BREAKING CHANGES

• HTTPS requests made while fetching remote content (attachment href/path URLs, OAuth2 token endpoints, HTTP/HTTPS proxy CONNECT) now validate the server's TLS certificate by default. Requests to hosts with self-signed, expired, or hostname-mismatched certificates that previously succeeded will now fail. Opt back out per request with tls.rejectUnauthorized=false (transport options, or a per-attachment tls option).

Bug Fixes

• replace deprecated url.parse with a WHATWG URL wrapper (0c080fb)
• validate TLS certificates by default when fetching remote content (6a947ac)
