archive threads with middle click

[tarik02]

What Changed

Middle-clicking a sidebar thread now archives it.

Why

Faster thread cleanup without changing normal left-click navigation or context menu behavior.
Everyone do similar: browsers/editors close tabs on middle mouse click.

Note

Low Risk
Low risk UI interaction change localized to the sidebar thread row; main risk is unintended interference with mouse events (e.g., selection/navigation) on different browsers/platforms.

Overview
Adds middle-click (mouse button 1) handling on sidebar thread rows to archive a thread directly. A mousedown handler prevents the default middle-click behavior, and an auxclick handler stops propagation, clears any pending archive confirmation state, and calls attemptArchiveThread for the clicked thread.

Note

Archive threads with middle click in sidebar

Adds middle-click support to SidebarThreadRow in Sidebar.tsx. A mousedown handler prevents the default browser scroll behavior, and an auxclick handler calls attemptArchiveThread on the target thread while clearing any pending archive confirmation.

Middle-click bypasses user's archive confirmation preference

Low Severity

The handleRowAuxClick handler directly calls attemptArchiveThread without checking appSettingsConfirmThreadArchive. The existing archive UI (icon button click) respects this user setting by routing through handleStartArchiveConfirmation when enabled, requiring an explicit "Confirm" click before archiving. Middle-click silently ignores this preference, which is especially risky since middle-click can be accidentally triggered during scroll-wheel usage.

Approvability

Verdict: Needs human review

This PR introduces a new user-facing feature (middle-click to archive threads) and has an unresolved comment identifying that it bypasses the user's archive confirmation preference setting, which is a behavioral inconsistency that warrants review.

Middle-click archives running threads, showing confusing error toast

Medium Severity

The handleRowAuxClick handler doesn't check isThreadRunning before calling attemptArchiveThread. All other archive paths in this component are guarded by !isThreadRunning — the archive buttons are only rendered when the thread isn't running (line 653). The middle-click bypasses this, causing archiveThread to throw "Cannot archive a running thread," which surfaces as an unexpected error toast to the user instead of being silently prevented.
