Subject: [PATCH] Update URL fragment to only appear when connected
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Only set URL fragment when mcpClient is connected
- Set default fragment based on server capabilities priority (resources > prompts > tools > ping)
- Clear fragment when disconnected to prevent stale routing state
