Application Store documentation and sample app

[RomansP]

Hello

We have developed two minimalistic versions of a single-page template app:
1.) Notes Pico, the simplest, using Pico CSS for a lightweight, semantic
UI without JavaScript dependencies,
and
2.) Notes, a simple yet feature-rich version with Bootstrap CSS and
JavaScript for a polished, interactive design.

Both apps contain a single index.lp file, combining Lua backend logic
and HTML templating, with detailed comments and README files for
easy modification; the entire source code can be copied and pasted
for AI-driven analysis or enhancements.

Difference:
Notes Pico is ultra-light and classless,
while Notes offers richer components and interactivity
but requires more markup.
