WebSocket, now editable — not just readable

• Rewrite, drop or pause WebSocket frames with rules that match on connection URL, payload text and direction. Catch a frame mid-flight, edit the payload, send it on — the same control you already have over HTTP requests.
• Ping/pong frames are hidden by default, so a chatty heartbeat no longer buries the messages you opened the tab to read. One tap shows them again.
• Search inside bodies and headers, not just URLs. Toggle it on from the search bar when you need to find that one request by what it contains.
• Break on the next call only: a one-shot breakpoint disarms itself after it fires, so the rest of your traffic flows through untouched.

Fixes
• Fixed a crash that could make the script editor unusable after importing a file or URL containing malformed characters.
• Fixed a crash when the file picker was opened twice in a row — most often on the certificate screen.
• A script requesting a relative URL now fails inside the script instead of closing the app.
• The free trial now appears correctly on the subscription screen.
