- Make publish endpoint idempotent: return success if same content
already exists instead of VERSION_EXISTS error (fixes retry issues)
- Always refresh tools page after publish dialog closes
- Consolidate My Tools page to group versions by tool name
- Show version count and list instead of separate rows per version
- Sum downloads across all versions for accurate totals
