The `claude mcp add` command fails with "already exists" when the server
is already registered. Additionally, configs written by setup/update used
a bare package name without @latest, causing npx to serve stale cached
versions indefinitely.
🔧 CLI registration:
- Remove existing entry before re-adding for Claude Code (both setup and update flows)
- Silently ignore removal errors when entry doesn't exist yet
⚡ Auto-update via @latest:
- Write @latest suffix in JSON configs, CLI commands, and manual instructions
- Smart detection in update flow: skip if config already has @latest,
offer migration if pinned, offer creation if missing
🎯 Users who run setup or update now get configs that always fetch the
newest version on MCP client restart, eliminating the stale-cache problem
without requiring manual npm cache clearing.
