Subject: [PATCH] fix: Fix node_id string slice syntax error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Final fix for compilation:
- node_id generation: uuid[0..8] → chars().take(8).collect()
- Split into two lines for clarity:
  let uuid_str = uuid::Uuid::new_v4().to_string().replace('-', );
  let node_id = format!("node-{}", uuid_str.chars().take(8).collect::<String>());

Compilation now successful ✅
All string slice errors fixed ✅

- src/server.rs (line 836-837: node_id generation)
