[FEATURE]: Show last active timestamps in desktop chat list

[Salloxy]

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

Please add compact timestamps to the OpenCode Desktop chat/thread list, showing when each chat was last active or last opened.

In the desktop app, the sidebar currently shows chat titles but not when they were used. This makes it hard to find the right chat when several sessions have similar names or when coming back after a few days.

A small relative timestamp, like 1d, 2d, or 1w, beside each chat would match the pattern used by many chat apps, including Codex Desktop. This request is specifically for desktop chat threads in the sidebar, not timestamps on individual messages and not CLI session output.

This issue might be a duplicate of existing issues. Please check:

Thanks for checking. I do not think this is a duplicate of #16341.

#16341 is about the subagent session picker opened with ctrl+x. This request is specifically for the main OpenCode Desktop chat/thread list in the left sidebar, where normal chat threads are shown.

The ask is to show a small last-active/last-opened timestamp next to each desktop chat thread, similar to Codex Desktop and other chat apps, so it is easier to find the right conversation to resume.
