Chat messages rendered URLs as plain text. Now http/https URLs render as clickable links that open in the system browser (xdg-open). - New pure `sanitize::linkify` splits an (already-sanitized) message into text/URL segments: conservative — only http:// and https:// runs, ending at whitespace, with trailing prose punctuation peeled back out; reassembling the segments reproduces the input exactly. +6 unit tests. - Chat render uses iced `rich_text` with link spans + `on_link_click`. - `OpenUrl` handler re-validates the http(s) scheme (defence in depth) before spawning xdg-open with the URL as a single argv entry (no shell, no injection). Linkify only runs after `sanitize_chat`, so control/format chars are already gone. 214 lib tests green, clippy clean. Manual check: send a message with a URL, click it.
