feat(rts-egui): pipeline 3D wgpu (scene pass) + fixes de codegen (gcell) + net nonblocking

[MarcosBrendonDePaula]

O que tem aqui (13 commits)

Trabalho feito localmente enquanto eu construía o editor de jogos (rts-game) em cima do motor. Abro como branch/PR porque o origin/main divergiu (36 commits novos, incl. um scene3d paralelo) e um merge no main precisa de conciliação humana — ver aviso de conflito abaixo.

rts-egui — pipeline 3D wgpu (scene pass)

• 351e9ec2 pipeline 3D wgpu completo + 5 primitivos (egui.meshUpload/drawMesh/setCamera/setLight)
• 5a7fb635 specular Blinn-Phong
• 6d360e50 skybox procedural (gradiente + estrelas)
• 4c324d21 luz pontual + flag emissivo por objeto
• f0eb61c6 shadow map direcional (PCF) + textura procedural
• 701a25a9 egui.winWidth/winHeight (tamanho lógico vivo)
• ee259c82 scene pass sem backface culling (cull_mode None) — necessário p/ meshes .obj de winding inconsistente

codegen — 2 fixes reais de bug (com repro no editor)

• 41990a4a nomes de classe/fn de usuário (Transform/Duplex/…) sombreiam shims do prelude (dedup em merge_programs)
• 7b3727f7 const/let de módulo lido dentro de função resolve (promoção a gcell)
• af57caae let/const aninhado no __rtsn_main não aliasa mais a gcell global (fix block_depth; zero regressão na suíte TS)

net

• 287befe9 tcp_set_nonblocking + sentinela -2 (WouldBlock) no tcp_recv — usado pelo controle WebSocket non-blocking do editor

⚠️ Aviso de conflito — scene3d paralelo

O origin/main já tem um scene3d próprio no rts-egui (src/scene3d/math3d.rs, render_backend.rs) feito em paralelo. Esta branch tem src/frame/scene3d.rs. Os dois precisam ser conciliados à mão antes de mergear. Overlap também em lower.rs (meu fix de gcell vs codegen deles), frame/gpu.rs, frame/mod.rs, lib.rs.

Os fixes de codegen (gcell/prelude-shadow) e o net nonblocking são independentes e provavelmente aplicam limpo — dá pra cherry-pickar separado se o scene3d for descartado em favor do de vocês.

Merge com origin/main feito — conflitos resolvidos, zero regressão medida

Integrei os 36 commits do origin/main nesta branch (merge ed4ac05c). Agora o PR é mergeável sem conflito (main virou ancestral).

2 conflitos, ambos em rts-egui — resolvidos mantendo o scene pass 3D desta branch (frame/scene3d.rs: shadow PCF, luz pontual, skybox, specular, emissivo; namespace egui.mesh*/drawMesh/setLight/setShadow). A implementação gpu3d paralela do main (src/scene3d/ + namespace gpu3d) foi removida da fiação porque colide no mesmo campo RenderState.scene e o editor consumidor depende do namespace egui.*. O scene3d do main segue intacto no histórico do próprio main — se preferirem o gpu3d, dá pra reverter esta escolha pontual.

O codegen (lower.rs, com o fix de gcell af57caae + as mudanças do main) auto-mergeou limpo.

Regressão: nenhuma. Build completo compila (exit 0). Suíte TS local: 2443/2452 testes. As 8 falhas foram auditadas contra o baseline origin/main (commit 4bd293b8, rebuild limpo):

• 1 (nodespace_fs_readdir) era lixo de dir temp da rodada anterior — passa após limpar.
• Os outros 7 (function_global, node_fs_*, node_crypto_basic, crypto_streaming_hash, node_string_decoder_full) já falham idênticos no origin/main — cluster node/crypto pré-existente, não introduzido por este merge.

Enxerto do bom do gpu3d (não descartei tudo do outro lado)

Revisitei o gpu3d do origin/main a fundo. Em shading o nosso scene pass é superset (shadow PCF, luz pontual, specular, skybox, textura, emissivo, instancing) e o depth buffer já existe nos dois — mas o gpu3d tinha 3 coisas boas que o nosso não tinha, agora enxertadas na nossa base (adaptadas à convenção left-handed):

• egui.setCameraLookAt(eye, target, fov, aspect, near, far) — câmera look-at NaN-safe (up alternativo ao olhar reto pra cima/baixo, em vez de gimbal-lock). Melhor pro "frame selected" do editor. near/far explícitos.
• egui.setClearColor(r,g,b) + setSkybox(on) — fundo chapado desligando o skybox procedural (gap real: viewport de editor quer fundo neutro, não starfield).
• perspective_lh() compartilhado + 4 testes unitários do math 3D (projeção clip / base ortonormal / reto-pra-baixo sem NaN / translação pura), validados por check rustc isolado.

O doc gpu3d-scene-pass.md (que veio do merge) foi marcado como superseded, apontando pra API viva egui.*.

Suíte TS: 2444/2452, zero regressão nova.
