[Feature Request] Web UI: no way to delete a conversation/session

[HanGe88]

Problem

In the DSH Web GUI, there is NO way to delete a conversation (session). The session row's "..." context menu only offers Rename, Fork, and Archive. There is no Delete option - unlike workspace rows, which do have a Delete action.

Expected behavior

A way to delete a conversation from the sidebar, for example:

• A "Delete" item in the session context menu (with a confirmation dialog), that removes the session data permanently, and/or
• A trash / recycle-bin mechanism with restore, consistent with the existing Archive feature.

Current workaround

Session data lives under ~/.dsh/sessions//session-/session.jsonl.zstd . Deleting that folder manually removes the conversation, but this is not discoverable and is unsafe while DSH is running.

Environment

• DSH version: 0.1.0-rc.6 (web UI, http://127.0.0.1:3080)
• OS: Windows 11

Related code

• dsh-client-ui-workspace - SessionNodeItem context menu only defines rename / fork / archive items (menu.archiveSession), no delete item.
• Workspace rows (ProjectRowItem) do have a delete item, so the pattern already exists.
