RSVP Nano v0.0.5

This release focuses on making everyday reading more reliable, especially for large books and real SD-card libraries.

Highlights

New indexed SD streaming reader for long books, with sidecar indexes so very large .rsvp files can open without loading the whole book into RAM.
Clearer loading screens and graceful book-opening failures, including readable status text while indexing or preparing files.
SD-card folder repair now asks before changing the card.
OTA checks can run in the background, while firmware installs still ask for confirmation.
RSS errors now use plainer language instead of raw HTTP-style codes.
Optional on-screen reading labels for battery, chapter progress, and book progress.
Rewind control stays visible while reading or paused.
Battery label can cycle between percentage, time remaining, and voltage.
Low-battery warning and critical battery shutdown protection.
Standby mode with selectable display options: Game of Life, Maze, Voronoi, or screen off.
Better punctuation handling for ellipses and hyphenated sentence breaks.
Improved Latin-script character handling for Spanish and other European languages.
Added slower reading speeds below 100 WPM in 10 WPM steps.
