Markdown links in responses are not clickable in terminal (Ghostty) — need raw URL fallback or OSC 8 hyperlinks

Environment

• Claude Code version: 2.1.210
• Platform: macOS (Darwin 25.5.0)
• Terminal: Ghostty (TERM_PROGRAM=ghostty, TERM=xterm-ghostty)

Bug

Markdown inline links ([text](url)) in assistant responses are not clickable and do not surface the raw URL in a usable way in the terminal. When the assistant replies with a markdown link, the rendered output shows the link text but the user cannot click it or easily copy the underlying URL.

Repro

1. Run Claude Code in Ghostty on macOS.
2. Ask a question whose answer includes a markdown link, e.g. a Buildkite or dashboard URL rendered as [build #45819](https://buildkite.com/...).
3. The rendered response shows the link text; the URL is not clickable (no OSC 8 hyperlink emitted or not usable), so the user has to ask the assistant to re-print the raw URL in a code block.

Expected

Either emit OSC 8 hyperlinks (Ghostty supports them) so the link text is clickable, or fall back to rendering the raw URL alongside the link text so it can be copied/cmd-clicked.

Impact

Any workflow where the assistant hands back URLs (CI builds, dashboards, PRs) requires a second round-trip asking for "the raw link". Workaround: instruct the assistant to always print raw URLs in code blocks.
