Toilet GodX Gang Interrupt

## 3.0.0 (Initial public release)

- **Renamed** to Toilet God X Gang — slash commands are now `/wc` and `/wheelchair`
- **Reliable readiness detection:** display and sound now share a single source of truth — if the icon lights up, the sound plays; if your kick is on cooldown, the icon greys out and stays silent
- **Own cooldown tracking:** works even when the cooldown API returns restricted values (Patch 12.x "Secret Values" in instanced content) — tracked via your own successful casts plus base cooldown data
- **Sound fires once per cast**, including chain-casting mobs with no gap between casts
- **Focus icon is now freely movable** with its own saved position (unlock, then drag); `/wc reset` restores the automatic anchor
- Added `/wc debug` diagnostics command for bug reports

## 2.0.0 (internal)

- Focus target support (second, smaller icon)
- Sound alert when an interrupt becomes possible

- Green flash on successful interrupt, yellow flash when your kick comes off cooldown mid-cast
- Optional states: out-of-range casts red, uninterruptible casts grey
- Smooth fades, icon border, localization (enUS/deDE), addon compartment entry

## 1.0.0 (internal)

- Initial version: class interrupt detection for all 13 classes (incl. spec/talent variants), cast state evaluation for the current target, cooldown overlay, glow, options window, test mode
