feat(eda): el Markdown del AutomaticEDA vuelca TODOS los datos del profile

El .md del grupo `eda` es la salida pensada para pegar a un LLM, así que debe
contener todo lo que el motor computó, aunque el PDF/PPTX (vista humana) resuman.
La evaluación 2053 detectó 6 datos que el .md perdía respecto al profile. Se
cierran de forma aditiva (el .md tiene MÁS que el PDF/PPTX, sin tocar esos
renderers ni los capítulos).

render_automatic_eda.py pasa el profile al serializador Markdown vía
meta['profile'] (un meta propio del MD; el de PDF/PPTX queda intacto).
render_md_impl.py añade un "Apéndice — Datos completos del perfil" al final del
documento, emitido solo cuando hay profile y degradando limpio cuando falta una
sección (lite sin modelos, profile sin correlaciones). El apéndice no se acopla
a los ids de capítulo (que editan otros agentes en paralelo).

Pérdidas cerradas:
1. Matriz de asociación COMPLETA: los N pares de correlations.pairs (no solo el
   top-17), incluidos correlation_ratio (num↔cat) y cramers_v (cat↔cat).
2. Numéricas: describe completo por columna — mean/median/mode/std/variance/cv,
   skew y kurtosis para TODAS (no solo las asimétricas), p1/p5/p25/p50/p75/p95/
   p99, iqr, min/max, outliers, distribution_type.
3. Re-expresión: nombra la transformación concreta (log1p/sqrt/yeo-johnson) con
   potencia, razón y alternativas, no un vago "considerar re-expresión".
4. KMeans: tabla scores_by_k (silhouette + inercia por k) marcando el k elegido.
5. Normalidad: el estadístico (stat) de cada test junto al p-value.
6. Encabezados de figuras de barras/scree dejan de heredar
   "Desde/Hasta/Frecuencia" del histograma; usan "Inicio/Fin/Valor" cuando el
   caption no es un histograma.

Test nuevo md_completeness_test.py: profile sintético, asserta los N pares de
correlación, skew/kurtosis de cada numérica, percentiles extendidos, log1p,
scores_by_k, stat de normalidad, headers de barras y los edges (sin modelos /
sin correlaciones / sin profile, defensivo).

Verificado con titanic (profile_level=full): 28 pares en la tabla (incl.
Sex↔Embarked cramers_v), 7 numéricas con skew+kurtosis, p5/p95/p99, scores_by_k
y JB/D'Agostino/Shapiro stat presentes. PDF/PPTX/manifest siguen saliendo.
Suite automatic_eda + render_automatic_eda_test: 134 passed.

+"""Tests for the Markdown completeness appendix (report 2053).
+
+The AutomaticEDA Markdown is the output meant to be *pasted into an LLM*, so it
+must carry EVERYTHING the engine computed — even the numbers the human-facing
+chapters (shared with the PDF/PPTX) drop for readability. ``render_md`` appends a
+full-data appendix built from ``meta['profile']`` that closes the six losses the
+evaluation found:
+
+1. the complete association matrix (every pair, incl. correlation_ratio /
+   cramers_v) — not just the top extremes;
+2. every numeric statistic for every numeric column (skew/kurtosis/percentiles);
+3. the concrete recommended re-expression;
+4. KMeans ``scores_by_k``;
+5. the normality test statistics;
+6. correct headers for bar/scree figure tables (not ``Desde/Hasta/Frecuencia``).
+
+Self-contained: a synthetic profile, no DuckDB, no heavy renderer.
