feat(web): add archive action to thread context menu

[maria-rcks]

What Changed

Added "Archive" option in context menu of threads in the sidebar.

Why

because (I believe) its better ux to have it there too, not only as an icon you have to click in the sidebar.

Note

Low Risk
Low risk UI change that adds a new sidebar context-menu action and a regression test; behavior is gated/disabled while a thread is actively running.

Overview
Adds an Archive action to the sidebar thread right-click context menu, wiring it to the existing attemptArchiveThread flow and disabling it when the thread has an active running turn.

Extends the browser test suite (ChatView.browser.tsx) with coverage that the context menu includes archive and that selecting it triggers the thread.archive dispatch over the websocket harness.

Note

Add archive action to thread context menu in sidebar

• Adds an 'Archive' item to the right-click context menu for threads in Sidebar.tsx, invoking attemptArchiveThread when selected.
• The archive option is disabled when the thread is currently running (status is running or an active turn is present).
• Adds a browser test in ChatView.browser.tsx verifying the context menu contains the archive item and dispatches a thread.archive command on selection.

Archive context menu skips user's confirmation preference

Medium Severity

The new "archive" handler in the context menu calls attemptArchiveThread directly, bypassing the user's appSettingsConfirmThreadArchive setting. The "delete" handler at line 1921 correctly checks appSettingsConfirmThreadDelete and shows a confirmation dialog via api.dialogs.confirm before proceeding. The archive handler needs the same pattern — checking appSettingsConfirmThreadArchive and prompting before archiving — to stay consistent with the sidebar's two-step archive confirmation flow.

Approvability

Verdict: Needs human review

An unresolved review comment identifies that the new archive handler bypasses the user's confirmation preference setting, unlike the existing delete handler. This inconsistency with user preferences is a substantive issue that should be addressed before merging.
