feat: externalize apps/analysis to Gitea repos, add analysis table

- Migration 007: repo_url on apps table + analysis table with FTS5
- Analysis struct, parser, CRUD, validation, hash computation
- Selective purge: remote-only apps/analysis preserved across fn index
- CLI: fn app list/clone/pull, fn analysis list/clone/pull
- search/show/list now include analysis results
- Apps removed from git tracking (content lives in Gitea repos)
- .gitkeep for apps/ and analysis/ dirs
- Bash functions: jupyter analysis pipeline, shell utilities
- Browser domain: CDP functions moved from infra to browser

+## Ejemplo
+
+```bash
+source init_uv_venv.sh
+venv=$(init_uv_venv /home/lucas/analysis/finanzas)
+echo "Venv creado en: $venv"
+
+# Idempotente — si ya existe, retorna la ruta sin recrear
+venv=$(init_uv_venv .)
+```
+
+## Notas
+
+Idempotente: si el venv ya existe con un python valido, retorna la ruta sin hacer nada. Prefiere uv por velocidad, usa python3 como fallback.
