Wave 1 de parallel-fix-issues integrada a master:
- 0025: text_editor_cpp_core + file_watcher_cpp_core
- 0026: gl_texture_load_cpp_gfx (vendor: stb_image v2.30)
Ademas se commitea WIP previo de master que estaba sin commitear (cambios
en shaders_lab, dag_*, framework, tokens, kpi_card, gl_loader.md, etc.)
para dejar HEAD buildable.
Notas:
- Algunos deps del gallery (button.cpp, toolbar.cpp, modal_dialog.cpp...)
siguen UNTRACKED — gating con FN_BUILD_GALLERY=ON (default OFF) para
que master build (sin flag) no los necesite.
- Build OK con y sin flag. fn index registra 904 functions.

- DagStep: preview_open flag (default false).
- dag_compile: emit `uniform int u_preview_target` and a series of
early-return branches at the start of fragColor selection. -1 (default)
falls through to the real Output-driven fragColor.
- dag_node_previews (new fn): per-node FBO keyed by editor_uid, lazy
created. Renders each node with preview_open=true to its FBO by
setting u_preview_target = step index. Texture exposed via
dag_preview_texture(uid) for ImGui::Image.
- dag_node_editor: small toggle button "[+] preview"/"[-] preview" in
each non-Output node; when open, ImGui::Image(96x64, V-flipped).
- dag_node_editor: double right-click on hovered node deletes it
(Output is protected).
- main.cpp: dag_previews_render after Canvas DAG; dag_previews_destroy
on shutdown.
Single GL program drives both the canvas and all thumbnails — moving
sliders never recompiles, only the topology change does.

The previous InvisibleButton captured mouse events, so you could drag
from the Functions palette into the canvas, but node dragging and
slider interaction inside the canvas stopped working.
Fix: watch the global drag-drop payload without an explicit target. When
the mouse releases LMB over the DAG window with a "DAG_NODE_TYPE"
payload active, queue an add at that canvas position. No button, no
capture.
Tests (compiled standalone with preprocessor defines):
- dag_compile: 6/6 asserts (empty, single gen, op chain, multi-source
blend, Output-driven fragColor, unconnected-Output fallback).
- dag_catalog: 8/8 asserts (uniqueness, per-kind input invariants,
exactly one Output, body_glsl present & returns, control param
indices valid).
Build with:
g++ -std=c++17 -Icpp/functions -DDAG_COMPILE_TEST cpp/functions/gfx/dag_compile.cpp cpp/functions/gfx/dag_catalog.cpp -o /tmp/dag_compile_test
g++ -std=c++17 -Icpp/functions -DDAG_CATALOG_TEST cpp/functions/gfx/dag_catalog.cpp -o /tmp/dag_catalog_test
