fix: add auto_cache to sshfs mounts to prevent stale reads in Emacs

sshfs kernel cache caused Emacs to show outdated file contents after
edits via Claude Code. Adding auto_cache invalidates cache when
mtime/size changes, fixing the stale data problem without sacrificing
performance.

-# Plan: Emacs Integration for napi — Remote File-Notify via TRAMP
-
-## Context
-
-Fénix wants **real-time awareness in Emacs** of student deliveries on zzz (qu3v3d0.tech). The GNU Emacs manual confirms that `file-notify-add-watch` works on **remote machines** via TRAMP — it runs `inotifywait` on the remote host through SSH and streams events back in real-time. No polling.
-
-This means: **no modifications to watcher scripts on zzz**, no reverse SSH tunnels, no Porthole/JSON-RPC. Pure Emacs, using built-in capabilities + a dedicated daemon.
-
-## Architecture
-
-```
-emacs --daemon=napi (local)
-    │
-    ├── TRAMP SSH → zzz:/home/*/python/    (ASIR1 — 21 dirs)
-    │   └── inotifywait running on zzz (auto-started by TRAMP)
-    │
-    ├── TRAMP SSH → zzz:/home/*/html/      (DDAW2 — 19 dirs)
-    │   └── inotifywait running on zzz (auto-started by TRAMP)
-    │
-    └── On file event → forward notification to `water` daemon
-        ├── Desktop notification (D-Bus)
-        ├── Sound alert (paplay)
-        ├── *napi-log* buffer (persistent log)
-        └── Minibuffer message
-
-emacsclient --socket-name=napi --eval '(napi-dashboard)'   ← interact
-emacsclient --socket-name=water --eval '(napi-log)'        ← view in main UI
-```
-
-## Prerequisites
-
-- `inotify-tools` installed on zzz (provides `inotifywait`) — **already present** (watchers use it)
-- SSH key access from local → zzz — **already working** (`ssh fenix@qu3v3d0.tech`)
-- Emacs 30.1 on local — **confirmed**
-
-## Implementation Steps
-
-### Step 1: Create `~/napi/emacs/napi.el`
-
-The core elisp package. ~200 lines. Key components:
-
-| Component | Purpose |
-|:----------|:--------|
-| `napi-watch-start` | Sets up TRAMP file-notify watches on all student dirs |
-| `napi-watch-stop` | Removes all watches cleanly |
-| `napi-notify` | Handles a file event: log + desktop notification + sound |
-| `napi-log` | Interactive: open `*napi-log*` buffer |
-| `napi-open-student` | Interactive: completing-read → open student dir/notas.md |
-| `napi-dashboard` | Interactive: overview of all students + last delivery |
-| `C-c n` prefix | Keybindings for all interactive commands |
-
-**Student name maps** (username → full name) embedded in elisp, mirroring watcher scripts.
-
-**TRAMP watch setup** — the core innovation:
-```elisp
-;; For each ASIR1 student:
-(file-notify-add-watch
-  "/ssh:fenix@qu3v3d0.tech:/home/jara/python/"
-  '(change)
-  #'napi--handle-event)
-
-;; 40 watches total (21 ASIR1 + 19 DDAW2)
-;; Each spawns a persistent inotifywait on zzz via SSH
-```
-
-**Event handler** filters noise (Thumbs.db, __pycache__, .tmp, etc.) and forwards clean notifications to `water` daemon via:
-```elisp
-(shell-command
-  "emacsclient --socket-name=water --eval '(napi--show-notification ...)' &")
-```
-
-**Reconnection**: TRAMP sends a `stopped` event when SSH drops. The handler auto-re-establishes the watch after a delay.
-
-### Step 2: Create systemd user unit for `napi` daemon
-
-File: `~/.config/systemd/user/emacs-napi.service`
-
-```ini
-[Unit]
-Description=Emacs daemon for napi student monitoring
-After=network-online.target
-Wants=network-online.target
-
-[Service]
-Type=forking
-ExecStart=/usr/bin/emacs --daemon=napi -l ~/napi/emacs/napi-init.el
-ExecStop=/usr/bin/emacsclient --socket-name=napi --eval "(kill-emacs)"
-Restart=on-failure
-RestartSec=30
-
-[Install]
-WantedBy=default.target
-```
-
-### Step 3: Create `~/napi/emacs/napi-init.el`
-
-Minimal init file for the `napi` daemon (not the full `~/.emacs.d/init.el`):
-
-```elisp
-;; Loaded ONLY by emacs --daemon=napi
-(load "~/napi/emacs/napi.el")
-(napi-watch-start)
-(message "napi: watching %d student directories on zzz" napi--watch-count)
-```
-
-### Step 4: Also load `napi.el` in `water` daemon
-
-Add to `~/.emacs.d/init.el` (near line 1478, following `funciones-art.el` pattern):
-
-```elisp
-(load "~/napi/emacs/napi.el")
-```
-
-This gives the `water` daemon the `napi-log`, `napi-dashboard`, `napi-open-student` commands and the `C-c n` keybindings — but **no watches** (those run in the `napi` daemon only).
-
-### Step 5: Verify `inotifywait` on zzz
-
-```bash
-ssh fenix@qu3v3d0.tech "which inotifywait && inotifywait --help | head -1"
-```
-
-## Files to Create/Modify
-
-| File | Action | Location |
-|:-----|:-------|:---------|
-| `emacs/napi.el` | **CREATE** | `~/napi/emacs/napi.el` |
-| `emacs/napi-init.el` | **CREATE** | `~/napi/emacs/napi-init.el` |
-| `emacs-napi.service` | **CREATE** | `~/.config/systemd/user/emacs-napi.service` |
-| `init.el` | **MODIFY** (1 line) | `~/.emacs.d/init.el` |
-
-**No modifications to zzz** — no watcher changes, no new SSH keys, no reverse tunnels.
-
-## Testing
-
-1. **Unit test** — load `napi.el` in `water`, call `(napi-notify ...)` manually
-2. **TRAMP watch test** — single watch on one student dir, touch a file on zzz
-3. **Full integration** — start `napi` daemon, simulate SFTP upload as student
-4. **Stress test** — confirm 40 concurrent TRAMP watches are stable
-5. **Reconnection** — kill SSH, verify watch auto-restores
-6. **UI test** — `C-c n l` (log), `C-c n s` (student), `C-c n d` (dashboard)
-
-## Risk: 40 Concurrent SSH/inotifywait Processes
-
-Each `file-notify-add-watch` via TRAMP spawns a separate `inotifywait` process on zzz. 40 watches = 40 persistent SSH channels + 40 inotifywait processes.
-
-**Mitigation**: TRAMP reuses SSH connections (ControlMaster). So it's 1 SSH connection + 40 remote processes. The zzz server's `inotify` limit (`fs.inotify.max_user_watches`) is typically 65536 — 40 is nothing.
-
-**Fallback**: If 40 watches proves unstable, consolidate to 2 watches on parent dirs (`/home/` with recursive) + filter events by path. Or switch to the emacsclient-via-SSH approach (see FINDINGS.md).

-** Explore the idea (as referred on above's gnu.org manual - link) "Notifications on File Changes", which states :
-
-"Several operating systems support watching of filesystems for changes to files or their attributes. If configured
-properly, Emacs links a respective library like inotify and others. These libraries enable watching of filesystems on the local machine. 
-
-**It is also possible to watch filesystems on remote machines**, see Remote Files in The GNU Emacs Manual. This does not
-depend on one of the libraries linked to Emacs. 
-
-Since all these libraries emit different events upon notified file changes, Emacs provides a special library filenotify
-which presents a unified interface to applications. Lisp programs that want to receive file notifications should always
-use this library in preference to the native ones. [..]
-
-
-the **bold** is mine ! ...
-
-*** Am i crazy saying that ~/napi could be running remotely, as long as a 'emacs -daemon=napi' which i could hook into an 'emacsclient' ?

-## Paso 6: Configurar nginx
-
-```bash
-sudo tee /etc/nginx/sites-available/dashboard > /dev/null << 'EOF'
-server {
-    listen 80;
-    server_name dashboard.qu3v3d0.tech;

-## Paso 7: Crear tabla-de-seguimiento.md
-
-```bash
-sudo tee /home/admin/html/dashboard/data/tabla-de-seguimiento.md > /dev/null << 'EOF'
-# Seguimiento - Grupo 2026
-
-## alumno01
-| Tarea | Estado | Fecha |
-|:------|:------:|------:|

-
-sudo chown admin:www-data /home/admin/html/dashboard/data/tabla-de-seguimiento.md
-sudo chmod 664 /home/admin/html/dashboard/data/tabla-de-seguimiento.md
-```
-
-**Formato alternativo con checkboxes:**
-```markdown
-## alumno01
-- [ ] Config nginx básica
-- [ ] JSON con CORS
-- [ ] Error pages
-- [ ] Caché estático
-```

-
-## Paso 8: Verificación
-
-```bash
-# 1. Permisos
-ls -la /home/admin/html/dashboard/
-ls -la /home/admin/html/dashboard/data/
-
-# 2. Nginx
-sudo nginx -t
-sudo systemctl status nginx
-
-# 3. PHP-FPM
-sudo systemctl status php*-fpm
-
-# 4. Test htpasswd
-htpasswd -v /etc/nginx/.htpasswd_sftp alumno01
-
-# 5. Test curl
-curl -u alumno01:alumno01 http://localhost/dashboard/api.php
-```
-
-**✅ Debe retornar:**
-```markdown
-# Seguimiento - Grupo 2026
-
-## alumno01
-| Tarea | Estado | Fecha |
-...
-```
-
----
-
-## Paso 9: Test en navegador
-
-1. Abrir: `http://dashboard.qu3v3d0.tech`
-2. Login: `alumno01` / `alumno01`
-3. Debe mostrar solo la sección de alumno01
-4. Probar con alumno02, alumno03...

-## Troubleshooting
-
-### Error 401 Unauthorized
-
-```bash
-# Verificar htpasswd
-ls -la /etc/nginx/.htpasswd_sftp
-grep alumno01 /etc/nginx/.htpasswd_sftp
-htpasswd -v /etc/nginx/.htpasswd_sftp alumno01
-```
-
-### Error 403 Forbidden
-
-```bash
-# Verificar permisos
-ls -la /home/admin/html/dashboard/
-ps aux | grep nginx  # Usuario debe ser www-data
-```
-
-### PHP no procesa
-
-```bash
-# Verificar PHP-FPM
-sudo systemctl status php*-fpm
-ls -la /var/run/php/php*-fpm.sock
-sudo tail -f /var/log/nginx/dashboard-error.log
-```
-
-### Página en blanco
-
-```bash
-# Test API directamente
-curl -u alumno01:alumno01 http://dashboard.qu3v3d0.tech/api.php
-
-# Ver consola navegador (F12)
-# Verificar que marked.js carga correctamente
-```
-
-### Usuario ve datos de otros
-
-```bash
-# En api.php, agregar debug temporal:
-echo "DEBUG: User = $user\n";
-
-# Verificar que ## username coincide exactamente
-# (sin espacios extras, case-sensitive)
-```
-

-## Extensión: Notificación XMPP
-
-Notificar cuando profesor actualiza la tabla:
-
-```bash
-# Script watcher
-sudo tee /usr/local/bin/dashboard-notify.sh > /dev/null << 'EOF'
-#!/bin/bash
-WATCH_FILE="/home/admin/html/dashboard/data/tabla-de-seguimiento.md"
-inotifywait -m -e close_write "$WATCH_FILE" | while read event; do
-    /usr/local/bin/xmpp-notify.py "📊 Tabla actualizada por el profesor"
-done
-EOF
-
-sudo chmod +x /usr/local/bin/dashboard-notify.sh
-
-# Servicio systemd
-sudo tee /etc/systemd/system/dashboard-notify.service > /dev/null << 'EOF'
-[Unit]
-Description=Dashboard Update Notifier
-After=network.target
-
-[Service]
-Type=simple
-ExecStart=/usr/local/bin/dashboard-notify.sh
-Restart=always
