[Bug] OSC 8 hyperlinks for file paths missing in assistant responses since 2.1.216

Bug Description
File paths in assistant responses are no longer emitted as OSC 8 hyperlinks — regression between 2.1.212 and 2.1.216.
Environment: Claude Code 2.1.216 (native install), Linux, GNOME Terminal, TERM=xterm-256color, plain terminal (not VS Code).

Expected: absolute file paths referenced in Claude's responses (inline code) are Ctrl+clickable, as they were last week on 2.1.209/2.1.212 in the same terminal.

Actual: paths render as plain text, no hyperlink escape emitted, nothing underlines on hover.

Terminal ruled out: running ! ls --hyperlink=always <dir> inside the same session renders Ctrl+clickable OSC 8 links correctly, so the terminal and the bash-passthrough both handle OSC 8 — only the assistant-message renderer stopped emitting them.

Possibly related: #70161 (statusline OSC 8 regression in 2.1.181), #79485 / #69008 (requests to emit OSC 8 for file paths).
