- Rename splash2.md -> splash.md so the tracked doc matches what aichat
references via include_str!/read_to_string (a clean clone now builds).
- Fix the live-read path (CARGO_MANIFEST_DIR was ../../../ = one dir above
the repo, loading a stale doc); now ../../splash.md -> repo-root glass doc.
- Full repaint (cx.redraw_all) on Clear/remove so self-managed glass overlay
draw lists aren't left composited stale.
