move demo/ to docs/tutorial/, commit assets, consolidate TUI docs

- demo/ renamed to docs/tutorial/ (tapes, scripts, TUTORIAL.md)
- docs/tutorial/assets/ added to git (51 MB of GIFs + PNGs); removed
  /demo/assets/ from .gitignore so images render on Codeberg
- docs/tui-reference.md removed; its hotkey tables merged into a new
  "Hotkey Quick Reference" section at the end of TUTORIAL.md
- TUTORIAL.md: updated install section (mage buildDocker, no
  GOTOOLCHAIN=auto), fixed README relative path (../../README.md),
  updated internal tapes/scripts/assets path prose
- README.md: updated all demo/ image paths and links to docs/tutorial/;
  TUI and recording-modes links now point to TUTORIAL.md anchors
- AGENTS.md: updated demo/ references to docs/tutorial/
- Magefile.go: updated demoDir/demoTapesDir/demoScriptsDir/demoRunTape/
  demoSudoKeepers constants to docs/tutorial/ paths
