Allow disabling automatic conversation title renaming

Problem

Claude Code automatically renames chat/conversation titles during the session. This is disruptive for users who intentionally name their chats (e.g., prefixing with project names like "WELLTA:", "RIOS:", etc.).

The title gets overwritten multiple times during a conversation, losing the user's original naming convention.

Expected behavior

A setting to disable automatic title renaming, e.g.:

{
  "titleAutoRename": false
}

Or at minimum, only rename once at the start and never again during the session.

Environment

• Claude Code VS Code extension
• Claude Opus 4.6 (1M context)
• Linux
