SkyChains

Skychains-1.21.1-1.4.0

- Added client commands: /skychains on, /skychains off`, /skychains wings on, and /skychains wings off.
- Added independent wing graphics settings: Detailed, Balanced, and Fast.
- Added /skychains wings graphics detailed|balanced|fast and a Wing graphics button in the settings screen (K).
- Fast mode reduces wing geometry and skips wing chains, the armour overlay, and animated colour flow for all wings viewed by this client.
- Commands save settings immediately; the wing graphics preference is restored after restarting the game.
- Wing graphics are viewer-local and do not overwrite other players' cosmetic preferences.

Geometry checks measured 41,060 vertices per side in Detailed with chains enabled, 25,092 in Balanced, and 6,464 in Fast (about 84% fewer than Detailed). These figures are geometry counts, not an FPS benchmark.
