data_table: declarative cell renderers Phase 1 (Badge/Progress/Duration/Icon)

Adds TableInput.column_specs sidecar field enabling apps to declare Badge,
Progress, Duration and Icon renderers per column without writing ImGui inline.
Back-compat: apps without column_specs compile and behave identically.

- data_table_types.h: CellRenderer enum, BadgeRule, IconMapEntry, ColumnSpec types
- data_table.cpp: hex_to_imcolor helper, icon_name_to_glyph static map (~30 Tabler icons),
  draw_cell_custom dispatcher, integration in Stage-0 and Stage-N cell loops and draw_extra_panel
- Bump version 1.0.0 -> 1.1.0 with capability growth log
- cpp/tests/test_column_specs.cpp: 5 smoke/linker tests (back-compat + 4 renderer types)
- cpp/tests/CMakeLists.txt: register test_column_specs target linked against fn_table_viz
- types/core/{cell_renderer,badge_rule,icon_map_entry,column_spec}.md: registry type mds
- docs/capabilities/data_table_renderers.md: canonical doc with end-to-end examples
- docs/capabilities/INDEX.md: added data-table-renderers group

All tests green: test_column_specs 5/5, test_fn_table_viz_smoke 8/8,
tql_emit 41/41, tql_apply 88/88, Wave-1 tests 8/8.

#include "viz/data_table.h"
#include "core/data_table_types.h"
// --- Setup (una vez) ---
data_table::TableInput t;
t.name = "orders";
t.rows = num_rows;
t.cols = num_cols;
t.cells = cells_ptr; // row-major flat array, owner externo
t.headers = {"id", "amount", "status"};
t.types = {data_table::ColumnType::Int,
data_table::ColumnType::Float,
data_table::ColumnType::String};
data_table::State st; // persiste entre frames
// --- Render (cada frame) ---
ImGui::Begin("Orders");
ImGui::BeginChild("##tbl", ImVec2(-1, -1));
data_table::render("##orders", {t}, st);
ImGui::EndChild();
ImGui::End();
```
## Cuando usarla
Cuando una app necesita tabla con filtros + agregaciones + viz + joins sobre datos en memoria. Reemplaza `ImGui::BeginTable` inline + toda la logica TQL manual. Sustituye directamente el include del playground (`tables/data_table.h`) cambiando solo el path a `viz/data_table.h`.
## Gotchas
- **ImGui + ImPlot context activos**: `render()` llama a APIs de ambas librerias. Llamar fuera de un frame activo causa UB.
- **State no stack-local**: `State` contiene el historial de drill, pipeline de stages, cache de stats y buffers de UI. Declarar en el stack del frame reset todo el estado del usuario en cada frame.
- **Drill-down propaga en State**: `st.active_stage` y `st.stages` se mutan por click en charts. El caller puede leer `st` tras `render()` para reaccionar.
- **Thread-safety**: `render()` usa `static thread_local` para buffers intermedios. Llamar solo desde el main thread de ImGui.
- **TableInput owner externo**: `cells` es un puntero raw al array del caller. Los datos deben sobrevivir durante toda la llamada a `render()`. No pasar puntero a vector que puede reallocarse.
- **Ask AI modal (llm_anthropic)**: el boton "Ask AI" usa un stub interno de `llm_anthropic` que retorna error por defecto. Para activar la feature real, compilar con `-DFN_LLM_ANTHROPIC=1` y proveer `infra/llm_anthropic.h` en el include path. Pendiente Wave 4: promover al registry.
- **FN_TQL_DUCKDB**: modo SQL del Ask AI requiere compilar con `-DFN_TQL_DUCKDB=1` y la libreria DuckDB disponible.
## Notas
No hay tests unitarios directos: `render()` requiere ImGui + ImPlot context activos (imposible sin ventana GL). Cobertura via:
1. `cpp/apps/primitives_gallery/playground/tables/` — playground original con self_test.cpp y e2e_run.sh.
2. Wave 4: migration self-tests en las apps que migren desde el playground.
**Estado Wave 3.5 (issue 0081-I):**
- Todos los includes del playground (`data_table_logic.h`, `tql.h`, `tql_to_sql.h`) eliminados. `data_table.cpp` compila sin el playground en el include path.
- `tql::apply` firma extendida ya en `tql_apply_cpp_core` (wave anterior). Resuelto.
- `tql_to_sql` promovido a `core/tql_to_sql.h`. Resuelto.
- `data_table_logic` helpers (row_to_tsv, drill, view_mode, etc.) declarados como `static` en `data_table.cpp`. No son API pública.
- `State::ensure_stage0/raw/active` implementados en `compute_stage.cpp`.
- `ColStats` struct: usa el de `compute_column_stats_cpp_core`. Unificado.
**Deuda tecnica restante (Wave 4):**
- `llm_anthropic` (Ask AI modal, issue 0080): stub interno activo. Promover a `cpp/functions/infra/llm_anthropic` para activar feature real.
- `FN_TQL_DUCKDB`: modo SQL del Ask AI sin soporte en stub. Requiere DuckDB + flag de compilacion.
- `column_specs` TQL roundtrip (Phase 2): actualmente caller-managed. No persisten en TQL emit/apply. Planificado en issue 0081-O.
## Capability growth log
v1.1.0 (2026-05-15) — declarative CellRenderer (Badge/Progress/Duration/Icon) via TableInput.column_specs sidecar. Back-compat preservado: apps existentes sin column_specs siguen funcionando sin cambios.
