- Switch config format from JSON to TOML (tomllib built-in on 3.11+,
tomli fallback for 3.10) so the generated config can include comments
- Write an annotated config.toml on first run with descriptions for every
knob/button and hints for all available actions
- Promote playerctl from optdepends to depends so media buttons work
out of the box
- Default buttons 1–3 now pre-configured for playerctl previous/play-pause/next
- Rename contrib/config.example.json → config.example.toml with full
TOML rewrite including per-knob LED colour override examples
- Log a migration hint when a legacy config.json is detected
- Add per-knob RGB LED configuration, validation, and color interpolation
- Add build_led_packet, send_leds, all_led_colors to turnupd
- Update config with VALID_LED_MODES, _validate_color, _validate_leds
- Update contrib/config.example.json with LED configuration examples
- Remove legacy root-level config.py and turnupd.py (moved to src/)
