Kestrel ESP (WallHack)

First release for 1.21.11.

1.21.11 replaced the rendering path the mod was built on: shaders are no longer registered by hand, entities are submitted to a collector instead of drawn, and the depth buffer is a GPU texture rather than a framebuffer to copy. The renderer was rebuilt on top of that, so everything the mod does on 1.20.1 works here:

• Outline in any colour, either only behind blocks or per-pixel around the hidden part alone.
• Hitbox wireframe with its own visibility rule.
• See-through model pass with full textures, 5-100 % brightness, per-pixel mode.
• Name tags in the group's colour, readable through terrain, at their own brightness — and the game's own white plate is hidden, so no name is written twice.
• Outline thickness and "thinner at range", both working per-pixel rather than only shifting the colour.

Requires Java 21.
