tolelom c930d4705d feat: add PNG decoder, query3/4, Capsule+GJK/EPA, friction, Lua engine API

- PNG decoder with self-contained Deflate decompressor (RGB/RGBA)
- ECS query3 and query4 for multi-component queries
- Capsule collider + GJK/EPA narrow phase for convex shapes
- Coulomb friction in physics solver
- Lua engine API bindings (spawn, position, entity_count)

Tests: 255 → 286 (+31)

PNG Decoder — Design Spec

Overview

voltex_renderer에 PNG 디코더를 추가한다. Deflate(Huffman+LZ77) 자체 구현으로 외부 의존 없이 PNG 파일을 파싱.

Scope

PNG 시그니처 + 청크 파싱 (IHDR, IDAT, IEND)
8-bit RGB (color_type=2), 8-bit RGBA (color_type=6)
Deflate 디코더 (zlib wrapper + fixed/dynamic Huffman + LZ77)
PNG 필터 복원 (None, Sub, Up, Average, Paeth)

Out of Scope

인터레이스 (Adam7)
16-bit depth
팔레트 (color_type=3)
그레이스케일 (color_type=0, 4)
Adler32 검증

Files

crates/voltex_renderer/src/deflate.rs — inflate (Create)
crates/voltex_renderer/src/png.rs — parse_png (Create)
crates/voltex_renderer/src/lib.rs — 모듈 등록 (Modify)

Test Plan

deflate: inflate fixed Huffman compressed data
png filters: each filter type reconstruction
parse_png: manually crafted 2x2 PNG roundtrip
RGB→RGBA conversion
