feat: funciones Bash — install_nbconvert, notebook_to_pdf, export_analysis_pdfs

+## Ejemplo
+
+```bash
+# Exportar todos los notebooks de un analisis
+./export_analysis_pdfs.sh finanzas
+
+# Con pattern especifico
+./export_analysis_pdfs.sh ml "notebooks/01_*.ipynb"
+
+# Via fn run
+fn run export_analysis_pdfs finanzas
+fn run export_analysis_pdfs ml "notebooks/01_*.ipynb"
+```
+
+## Flujo
+
+1. `assert_command_exists uv` — verifica que uv esta disponible
+2. `install_nbconvert` — instala nbconvert y playwright con chromium (idempotente)
+3. `notebook_to_pdf` — convierte notebooks al patron indicado a PDF en `notebooks/pdf/`
+
+## Notas
+
+El analysis debe existir previamente en `analysis/{nombre}/` con un venv inicializado. Los PDFs se generan en `analysis/{nombre}/notebooks/pdf/` por defecto. El pipeline usa `set -euo pipefail` — cualquier fallo detiene la ejecucion.
