Combat, Forge UI & Performance Update

This update improves combat clarity, refreshes the Forge, and reduces slowdown during crowded later waves.

• Improved performance from wave 6 onward, especially during heavy late-wave combat. • Reworked Forge buttons and confirmation windows to match the game’s dark fantasy style. • Reordered Forge tabs to Combine → Ascend → Strengthen. • Equipped items can now be unequipped directly from the Forge. • Upgrade previews now show clear stat gains, such as +1 Range. • Meteor Storm now casts every five seconds, with fewer meteors scattered across random nearby locations. • Added screen-edge chest icons to help you find unopened chests off screen. • Chest rewards now show rarity through colored borders instead of color-name labels. • Added a pulsing red screen warning below 25% health. • Increased early Raven damage. • Removed falling trees from waves 1–3.
