Replace example shows with numbered production shows and add sparkle flag

- Rename all show .txt files with NNN_ numeric prefix so order is explicit
  and controlled by filename (001_heartbeat_red through 006_party)
- Drop HOME_SHOW special-casing from convert_all.py; show 0 is simply the
  lowest-numbered file
- Add SHOW_FLAG_SPARKLE support: shows can declare '// flags: sparkle' to
  overlay random white flashes on top of the base color each frame
- Wire sparkle into led_controller and config.h (SPARKLE_CHANCE/FRAMES)
- Replace old placeholder/example shows with the six production shows

Show 0 is always 'blue_breath' — the home/reset show.
All other shows are sorted alphabetically and follow after it.
Show files must be named NNN_<name>.txt (e.g. 001_heartbeat_red.txt).
They run in numeric order; show 0 (the home/reset show) is the lowest-numbered file.
Show file directives (in comment lines):
// mode: single — play once, then advance to the next show (default: loop)
// flags: sparkle — overlay random white sparkles on this show
