[FEATURE] Confirmation dialog before deleting chat sessions (re-raising #43871)

Problem Statement

Re-opening this topic because the previous issue (#43871) was auto-closed
as stale, not because the problem was resolved. The underlying issue
still exists in version 2.1.181 (VS Code extension).

Deleting a chat session in the VS Code extension is a one-click,
irreversible action with no confirmation. Accidental clicks on the
trash icon permanently destroy conversation history — including
context-heavy mid-project sessions that cannot be reproduced.

• #62816, #63046, #63724

The repeated re-filing by different users over months shows this is
a persistent pain point, not a one-off complaint.

Proposed Solution

Any of the following would solve this:

1. A confirmation dialog before deletion (minimum viable fix)
2. A configurable setting: claudeCode.confirmDeleteChat: true | false
3. A soft-delete / trash with restore option (ideal solution)
