Add install-tui.sh library with boot scan, logo decrypt reveal,
bouncing Bitcoin symbol progress bar, and celebration strobe.
The installer sources it if available, falls back to plain text
if missing (easy revert: just remove the source line).
Animations: CRT power-on scan, BIOS memory check simulation,
3D ASCII logo with character-by-character decrypt reveal,
progress bar with ₿ bouncing DVD-screensaver style during
long operations, logo color party on completion, flashing
"REMOVE THE USB DRIVE NOW" warning.
