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 bash/functions/shell/exit_with_status.sh
+
+exit_with_status 5 5 0  # stdout: 0, exit code: 0
+exit_with_status 5 0 5  # stdout: 1, exit code: 1
+exit_with_status 5 3 2  # stdout: 2, exit code: 2
+```
+
+## Notas
+
+Funcion pura: no realiza I/O de sistema, no modifica estado global, no lee variables de entorno. El argumento `total_steps` se recibe para completitud semantica pero la logica solo depende de `ok_steps` y `failed_steps`. El valor se imprime a stdout ademas de usarse como exit code, de modo que el caller puede capturarlo con `$(exit_with_status ...)` o evaluar directamente con `exit_with_status ... ; echo $?`.
