0.9.0-preview.2026-09-16: clicking a space in the left sidebar no longer switches workspace (Windows)

Is this a reproducible bug?

• I confirm this is a reproducible bug, not a feature request, idea, question, contribution proposal, or direction check.
• I reproduced this bug on the version and environment reported below using the exact steps provided.

Current behavior

After upgrading to 0.9.0-preview.2026-09-16-2c29fb29e302, clicking a space row in the left sidebar does nothing at all: no highlight change, no workspace switch, the current workspace stays put.

This worked on 0.9.0-preview.2026-09-08-62431dbd033b and every build before it, and broke immediately after upgrading.

Expected behavior

Clicking a space row in the left sidebar focuses that space and switches the workspace, as it did on 2026-09-08 and earlier builds.

Reproduction

1. Launch herdr inside WezTerm with a session containing 2+ spaces
2. Click a different space row in the left sidebar

Nothing happens. Reproduced consistently across multiple attempts and restarts.

Impact

Mouse-clicking spaces in the sidebar is my main way of switching workspaces, so the new build is unusable for me.

Workaround: downgraded back to 0.9.0-preview.2026-09-08-62431dbd033b (repointed the current junction and PATH entry under ~/.herdr/packages/standalone/).
