Cursor Ring +

## 1.5
- Reworked secondary resources into class-specific modules that only load the implementation relevant to the current class.
- Added class/resource-specific colors and curved segment rendering for secondary resource rings, including dynamic max-resource updates.
- Rebuilt Death Knight rune handling with dedicated rune-state logic, continuous recharge updates, and DK-specific alpha-pop refill behavior.
- Added ring priority layout so the main ring stays centered, the cast ring takes the first outer slot, and the resource ring nests outside it.
- Reworked the GCD swipe to use native cooldown timing with ring-shaped swipe textures, avoiding secret-value taint while keeping the swipe on the main ring.
- Added support for modern empower/charge casts on the cast ring, including empower events, stage indicators, and staged tier coloring with hold-at-max accenting.
- Added per-class secondary resource palette overrides and improved full-state visibility while allowing DK runes to opt out of washout-style highlighting.
