issue 0029
Adds three new demos to the Core section of primitives_gallery:
- demo_tween: dropdown of all 16 Ease modes + animated plot showing the
curve and a moving marker that traverses t=0..1 in a loop.
- demo_bezier_editor: live editor with reset + ease-out / ease-in-out
presets, current control points displayed, slider over t showing
bezier_eval(curve, t).
- demo_timeline: 2 tracks (hue, amp) with mixed eases, live progress bars
showing track_value_at(current_time) updating each frame.
Wires the three demos into k_demos[] in main.cpp and adds the new sources
(plus the three function .cpp files) to CMakeLists.txt.
Demo nuevo en demos_sql.cpp: abre registry.db en SQLITE_OPEN_READONLY
(resolviendo via FN_REGISTRY_ROOT o cwd ascendente), monta
fn::SqlWorkbenchState con readonly=true y query inicial sobre la tabla
functions. Wire-up: entry en k_demos[] tras process_runner; declaracion
en demos.h; sources sql_workbench.cpp + demos_sql.cpp + link
SQLite::SQLite3 en CMakeLists.txt.

- demos_3d.cpp con dos demos:
* demo_surface_plot_3d: malla 64x64 de A*sin(fx*x)*cos(fy*y) con
sliders fx/fy/amp en tiempo real.
* demo_scatter_3d: 3 clusters gaussianos (N=500) coloreados por
cluster, semilla fija para reproducibilidad.
- demos.h: declara las dos demos en la seccion Viz.
- main.cpp: dos entradas nuevas en k_demos[] (Viz, tras heatmap /
table_view).
- CMakeLists.txt: anade demos_3d.cpp + surface_plot_3d.cpp +
scatter_3d.cpp al target.
Issue 0028.
Cobertura del catalogo visual:
- text_editor (Wave 1, 0025): demo solo del editor con dropdown GLSL/SQL/Cpp/Generic.
- file_watcher (Wave 1, 0025): demo solo del watcher con boton touch + log.
- gl_texture_load (Wave 1, 0026): ya tenia demo (Gfx).
- process_runner: tarea simulada en background con spinner.
- candlestick: 30 dias OHLC sintetico.
- gauge: 3 indicadores con sliders (CPU/MEM/GPU).
- heatmap: gaussiana 12x12.
- table_view: 6 funciones del registry como muestra.
El demo combinado anterior (text_editor + watcher) se separa en dos para
que cada entry del sidebar exhiba un solo primitivo. Mas claro y mas
indexable.
Total entries en gallery: 26 (antes 23).
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.

Tras integrar 0025 (que trajo la app entera) y 0026 (que solo añadio
demos_gl_texture.cpp + assets/sample.png + cpp/functions/gfx/gl_texture_load.*),
falta wire-up de la entrada nueva en los archivos compartidos del gallery.
- demos.h: declarar gallery::demo_gl_texture()
- main.cpp: entrada en k_demos[] con id "gl_texture", category "Gfx"
- CMakeLists.txt: añadir demos_gl_texture.cpp, gl_texture_load.cpp,
stb_image_impl.cpp, e include dir vendor/stb

- demos_text_editor.cpp: split horizontal con editor GLSL precargado a la
izquierda (boton Save to /tmp/fn_demo.glsl + dirty indicator) y panel de
eventos a la derecha (path, active flag, lista scrollable, boton clear).
Watcher activo sobre /tmp/fn_demo.glsl; reintenta el add() tras el primer
Save si el archivo no existia al iniciar.
- demos.h: declaracion de gallery::demo_text_editor()
- main.cpp: entry "text_editor"/"text_editor + watcher" en categoria Core
- CMakeLists.txt: anade demos_text_editor.cpp + sources de text_editor,
file_watcher y vendor TextEditor.cpp + include path de imgui_text_edit
Nota: la primitives_gallery NO se construye en este branch (sus deps —
button.cpp, toolbar.cpp, etc. — son untracked en master). El subdirectorio
se anade pero protegido por FN_BUILD_GALLERY=OFF para no romper builds.

App minima (no abre ventana ImGui) que crea/settea/lee text_editor y registra
un watch sobre /tmp/fn_smoke_test.txt para confirmar que TextEditor.cpp del
vendor + text_editor.cpp + file_watcher.cpp enlazan correctamente. Activada
por defecto si la carpeta existe (no requiere la primitives_gallery).
Tambien anade flag FN_BUILD_GALLERY (OFF default) para no romper el build
cuando la primitives_gallery no esta presente — sus deps (button.cpp,
toolbar.cpp...) son sources untracked en algunas branches.

Añade demos_gl_texture.cpp (carga assets/sample.png con la nueva
funcion gl_texture_load_cpp_gfx, muestra w/h/channels y sliders de
tint RGB + zoom UV via ImGui::ImageWithBg) y un PNG damero 256x256
generado para la demo.
Tambien registra apps/primitives_gallery como subdirectorio en
cpp/CMakeLists.txt (la app vive como WIP en master; aqui solo se
añade el hook de build).
Para integrarse, demos.h, main.cpp y CMakeLists.txt de la gallery
deben anadir respectivamente la declaracion gallery::demo_gl_texture(),
la entrada {"gl_texture", "gl_texture_load", "Gfx", &gallery::demo_gl_texture}
en k_demos[], y demos_gl_texture.cpp + cpp/functions/gfx/gl_texture_load.cpp +
cpp/vendor/stb/stb_image_impl.cpp + include de cpp/vendor/stb a sus sources.

- 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.

Canvas Code and Canvas DAG are now independent windows, each with its
own ShaderCanvas, FBO and compiled program. Both render every frame in
parallel. No more focus-based recompile — each source compiles when its
own content changes.

Remove Code/DAG toggle. Each panel lives in its own dockable window.
Active source (Code or DAG) is whichever window has focus; Canvas title
shows the current active source. Switching active source triggers an
immediate recompile so the canvas reflects the selected pipeline.

- cpp/functions/gfx/gl_loader.{h,cpp,md}: mini loader para OpenGL 2.0+
(Linux no-op via GL_GLEXT_PROTOTYPES, Windows wglGetProcAddress)
- Portar gl_shader/gl_framebuffer/fullscreen_quad/shader_canvas al loader
- CMakeLists: WIN32_EXECUTABLE para lanzar sin consola en Windows
- apps/shaders_lab/shaders_lab.exe: binario PE32+ precompilado

Añade soporte C++ al registry: vendor submodules (glfw, imgui, implot, tracy),
sistema de build con CMake y toolchains cross-platform, runner C++ en fn CLI,
parser de tests Google Test, y funciones bash para build Linux/Windows.
