* chore(ci): add clang-format gate, CODEOWNERS and agent collaboration rules * refactor(modules): clear remaining back-edges and split the largest TUs Three known dependency back-edges are gone (module_depgraph.py KNOWN_BACK_EDGES is now empty; --check passes with 0 violations, 0 cycles): - window -> graphics: window queries the new IWindowSurfaceHost capability (common/WindowSurfaceHost.h) instead of holding a Graphics pointer; Window::setGraphics was removed and all call sites updated. - window -> image: Window::setIcon was replaced by setIconRGBA(const uint8_t*, w, h); the window no longer decodes ImageData. - scene -> graphics: pickScreenAt / collectFrustumIdsAt implementations moved to graphics/ScenePicking.cpp (graphics -> scene is a legal downward edge); scene now depends only on spatial. TU splits (pure moves, verified identical method sets and brace balance): - vulkan/Graphics.cpp (5118 lines) -> Graphics.cpp (lifecycle), GraphicsPipeline, Graphics2D, Graphics3D, GraphicsMesh + shared GraphicsInternal.h. - scene/Scene.cpp -> Scene.cpp (script layer / host lifecycle / serialization) + SceneNodes.cpp + shared SceneInternal.h. Verified with a real build (MSVC 19.51, prebuilt third-party): full build green; window.* and Scene.* suites pass, including scene picking/culling and GPU cases. * refactor(graphics): narrow Graphics interfaces and clear public-header leaks Step 4 — interface segregation: - New lean interfaces: IGraphics2D, IGraphics3D, IResourceFactory, IPostFX (pure virtuals, forward-declared types only; graphics/Color.h extracted from Canvas.h so modules that only need the color type stop pulling Canvas.h). - Graphics now implements all four facets; consumers can depend on the narrow interface they use instead of the 129-method god class. - Migrated voxel (VoxelWorld::drawVisible -> IGraphics3D*) and model3d (ModelRenderer::buildRenderable(s) -> IResourceFactory&). - Graphics.h slims from 24 sub-header includes to a handful of small type headers + forward declarations; the destructor moved out-of-line so unique_ptr effect members are destroyed where types are complete. Step 5 — header leaks (module_depgraph.py '*' marks: 14 -> 7): - map/TileLayer.h, particles/ParticleEmitter.h, avatar/AvatarInstance.h, animation/SpineAnim.h, map/TileSystem.h, model3d/ModelData.h, model3d/ModelRenderer.h, audio/Audio.h + Source.h, image/ImageData.h + Image.h, dialogue/Dialogue.h, procgen Palette/OutputSpec/TextureRecipe/ PbrMaterial -> forward declarations, includes moved to .cpp. - voxel/VoxelWorld.h: terrain sampler Pimpl'd (unique_ptr + out-of-line destructor), removing the procgen header dependency. - gpgpu/vulkan backend headers stop pulling graphics/vulkan/Graphics.h. - Remaining '*' marks are deliberate: tiny POD/enum headers (GridConfig, MapObject, BlendMode, Color), an internal backend header (GraphicsInternal.h -> filesystem), and lean interface references. Verified with a full clean build (MSVC) and tests: window/Scene/voxel/ RenderSystem/Quad/shader/TextureSampler/resourceLifetime pass; broad suite only shows the pre-existing PHYSFS-init filesystem-environment failures. * feat(resources): revive ResourceManager as unified IAssetReloader-backed cache * fix(resources): leak ResourceManager singleton to avoid exit-time teardown crashes Cached CPU resources may own third-party handles (FreeType faces, Assimp scenes, image decode handlers) whose libraries are torn down at process exit in an unspecified TU order; destroying cached entries from the singleton destructor can segfault at exit (seen on CI Windows in model3d.materialApi.objMtl). Keep the singleton alive until OS reclaim; explicit unload()/clear() still release entries during the run. * refactor(devtools): consume business modules through capability interfaces DevTools / cmdline no longer include business-module headers, so trimming scene / physics / procgen / particles / audio / ui / graphics no longer requires disabling devtools, and devtools can be switched off with -DEVENGINE_MODULE_DEVTOOLS=OFF. New capability interfaces in common/: - ISceneQuery (scene) - host/node inspection + mutation + transform sync - IRenderCapture (graphics) - render status, PNG capture, camera control, visible-entity snapshot, entity-ID mask, G-buffer PNGs - IPhysicsQuery (physics) - 2D world lifecycle + ray casts - IProcgenQuery (procgen) - recipe listing, map/mesh generation - IParticlesQuery (particles) - emitter status + one-shot emit - IAudioQuery (audio) - volume / stop-all - IEditorHost (ui) - declarative editor host (used by cmdline too) Providers register in their module constructors. DevTools rewires McpServer (render/scene/procgen/physics/particles/audio/host tools), SceneInspect (now delegates to ISceneQuery + IRenderCapture) and RenderVision (uses IRenderCapture::capturePngDataUrl); cmdline/Mcp.cpp uses IEditorHost. manifest: devtools DEPS graphics scene physics procgen particles audio ui image event filesystem -> event; cmdline DEPS filesystem ui -> filesystem. Verified: full build green; devtools.mcp.* tests pass; broad suite shows only the pre-existing PHYSFS-init filesystem-environment failures. * style: apply clang-format to changed lines after dev merge * fix(webgpu): include RenderControl/TextureSampler explicitly after Graphics.h slimming * fix(webgpu): provide newFont/print stubs to satisfy IGraphics2D/IResourceFactory vtables * fix(common): make ProcgenQuery.h self-sufficient (cstdint/utility for GCC)

字体模块
脚本入口： eve.Font()
从文件或内存创建 FontData，并读取字形度量和位图。
基本用法
local font = eve.Font();
local data = font.newFontDataFromFile("fonts/game.ttf", 24);
对象关系与调用时机
Font 创建 FontData；FontData 保存 face 与字号，提供度量并按需栅格化 Glyph 到 ImageData。布局使用 advance/kerning，渲染资源应缓存。
目标导向指南
载入字体并计算布局
用 newFontDataFromFile(path, size) 创建字体数据；getWidth(text) 计算文本宽度，getLineHeight() 决定行距，居中前应先测量而不是估算字符数。
生成单个字形贴图
先用 hasGlyph(codepoint) 检查，再调用 newGlyphImageData(codepoint)。使用 getGlyphBearingX/Y() 和 getGlyphAdvance() 排版，不能只按位图宽度推进光标。
常见问题
- 按位图宽度排版：忽略 bearing、advance 和 kerning 会错位。
- 字体文件不存在仍继续：加载阶段应提供 fallback。
- 每帧创建 FontData：
newFontDataFromFile已走统一资源缓存（同一路径 + 字号共享一份 face，文件变化时原地刷新），但仍应避免每帧调用；newFontData(Data, size)的内存路径不缓存。
API 快查
下列方法名来自当前 Squirrel 绑定；同一模块创建的辅助对象（例如 World、Body、Source）的方法也列在这里。
getAscent()、getBaseline()、getDescent()、getFamilyName()、getFormat()、getGlyphAdvance()、getGlyphBearingX()、getGlyphBearingY()getGlyphCount()、getGlyphHeight()、getGlyphWidth()、getHeight()、getKerning()、getLineHeight()、getName()、getSize()getStyleName()、getWidth()、hasGlyph()、hasGlyphs()、newFontData()、newFontDataFromFile()、newGlyphImageData()
使用要点
- 模块对象和它创建的资源对象应保存在全局或实体状态中，不要在每帧重复创建。
- 带
update(dt)的系统应在eve_update调用；绘制方法应在eve_render调用。 - 参数约束、默认值和返回类型以对应模块头文件及
addFunc绑定为准；本文 API 快查与当前源码同步生成。
