Webui shows lower version than what it should. for example 1.18.18 is displayed as 1.18.17.

Description

Title:
WebUI displays incorrect version number (one lower than actual version / CLI)
Description:
There appears to be a small bug in how the WebUI calculates or displays the version number. It seems the WebUI always displays the last digit as -1 compared to the actual installed version.
Steps to reproduce / Example:

1. Install OpenCode version 1.18.18.
2. Check the version using the CLI: It correctly displays 1.18.18.
3. Open the WebUI and check the version there: It incorrectly displays 1.18.17.

Expected behavior:
The WebUI should mirror the correct version number as shown by the CLI (e.g., 1.18.18 instead of 1.18.17).

I see there are some other posts in the past about the same issue, even dating back to april 2025, and in some posts I see developers reaction as "Issue is fixed!". But as of today 16 August 2026, the issue is still ongoing, thats why I posted this bug report.

• start up the cli/tui by typing 'opencode' and see in bottom right that it shows the correct version.
• start up the webui by typing 'opencode serve --hostname 0.0.0.0 --port 8088' (example, you can fill in other ip or port).
• then in your webbrowser go to the opencode server, click on the top left 'home' button so that it shows the list of conversations, settings etc.
