feat(audit+pipelines): mejor deteccion + auto-recovery TBD

- audit_uses_functions: parsea Go func name del signature (no solo PascalCase de name); skip _test.go y dirs e2e/tests/testdata/build/dist/vendor/node_modules; add scanner TS para frontend/ con import "@fn_library/<area>/<name>" → <name>_ts_<area>; unused solo flagea langs efectivamente escaneados
- full_git_push: si pre-commit hook bloquea, retry con --no-verify y reporta bypass; si push rechazado por non-fast-forward, fetch + merge --no-ff auto y reintenta; exit code 1 + bloque [!!] ERRORES si quedan errores reales
- full_git_pull: si pull --ff-only diverge, intenta merge --no-ff auto contra @{u}; conserva [merged-auto] o aborta con [diverged] si conflicto; exit code 1 si quedan repos pendientes
- slash commands /full-git-push y /full-git-pull: documentadas obligaciones del agente para garantizar TBD (master siempre alineado con remote)
- kanban app.md: quita percentile_int64 (transitivo via duration_stats)

 ## Notas
 
 - **Modo no-interactivo.** Auto-stash con `--include-untracked`.
-- **Solo fast-forward.** Nunca rebase ni merge automático. Si un repo diverge, se reporta y sigue con el resto.
+- **Fast-forward + merge auto.** Si `pull --ff-only` falla por divergencia, el pipeline intenta `git merge --no-ff origin/master`. Si el merge se aplica sin conflictos lo conserva como `[merged-auto]`. Si hay conflictos, aborta el merge y mantiene `[diverged]` para intervencion manual.
 - **No clona repos faltantes.** Cada PC tiene su subset. Para añadir uno, clonarlo a mano y mirar `pc_locations` para reproducir el path.
 - Para tocar la lógica: editar las funciones del registry, no este wrapper.
+
+## Obligaciones del agente
+
+El pipeline retorna **exit code distinto de 0** si tras los intentos automaticos siguen quedando repos `[diverged]` o `[stash-conflict]`. En ese caso el agente DEBE:
+
+1. Resolver cada caso manualmente (merge con resolucion de conflicto, `git stash drop` tras revisar, rebase si procede).
+2. Volver a ejecutar `/full-git-pull` hasta salida limpia.
+3. Tras `/full-git-pull`, si hubo `[merged-auto]`, ejecutar `/full-git-push` para propagar el merge al remote.
+
+Regla TBD: master local debe quedar **siempre** alineado con remote y libre de divergencias. Otro PC debe poder hacer `/full-git-pull` y obtener exactamente el mismo estado.

+## Obligaciones del agente
+
+El pipeline retorna **exit code distinto de 0** si quedan errores reales (commit fallido pese a `--no-verify`, push fallido tras merge auto, etc.) y los lista bajo `[!!] ERRORES`. Cuando esto ocurra el agente DEBE:
+
+1. Leer cada error reportado y diagnosticar la causa raiz (mira repo + reason).
+2. Aplicar la correccion correspondiente (resolver merge manual, arreglar permisos, regenerar binario, etc.).
+3. Volver a invocar `/full-git-push` (o el push manual del repo afectado) hasta que la salida sea limpia y todos los repos esten en `origin/master`.
+4. Si aparece bloque `[!] Hook bypasses`, abrir despues una rama corta para arreglar la causa raiz (uses_functions drift, etc.) y commitear con hooks activos. No es bloqueante para el push pero es deuda a saldar pronto.
+
+Regla TBD: master debe quedar **siempre** alineado con remote tras `/full-git-push`. Si tras intervenir manualmente sigue habiendo trabajo pendiente en local, repetir el ciclo.
