BWR-Core

### Major Release 0.3.0

BWR-Core refactored into a clean library architecture with manual, transparent Line-of-Sight API.

#### What's Added:

- **ILOSProvider API** — single public interface for visibility checks between world positions.

- **LOSManager** — provider implementation using 3D Bresenham:

  - Fast, deterministic computation.

  - Minimal memory allocations.

  - Optional primitive cache (FastUtil).

  - Fully manual API: mods call only when needed.

#### What's Removed:

- Legacy render optimization system (RenderOptimizer).

- All server/client commands (/bwr, /bwr_render, etc.) — Core is now a library, not an integration layer.

- Config GUI and keybindings.

- Automatic event hooks and background computation.

- InstrumentationAPI auto-injection mechanism.

#### Architecture:

BWR-Core is now a **library** for use by other mods:

- Independent LOS usage from ExplosionGlass, Shadow, and other projects.

- No auto-registration; each mod decides when it needs a provider.

- Synchronous, thread-safe API.

#### For Mod Developers:

```java

// Creation and usage

com.coders.bwr.core.ILOSProvider los = new com.coders.bwr.core.los.LOSManager(true); // true = enable cache

boolean canSee = los.hasLineOfSight(world, posA, posB, /*ignoreTransparent*/ true);

```
