Tighten identity and trim trailing blank lines in coder-lite.

Tighten identity and trim trailing blank lines in coder-lite.

- Add an explicit `Item::system_message` to `CoderRuntimeSession::new` with
  strong identity constraints: do not identify as Google/Anthropic/OpenAI,
  do not mention model/training, never claim to be a large language model.
- Remove the hard-coded trailing blank line after assistant entries in tui.rs.
- Pop trailing empty `Line`s produced by ratatui-markdown so no extra spacing
  appears after assistant responses.
