fix(v1.8.0): CRITICAL - Fix ProGuard obfuscation causing data loss

CRITICAL BUGFIX:
- Fixed incorrect ProGuard class path for Note\$Companion\$NoteRaw
- Original v1.8.0 had specific -keep rules that didn't match actual JVM class name
- R8 obfuscated all NoteRaw fields (id→a, title→b, ...) → Gson parse failure
- ALL notes appeared lost after update (but were safe on disk/server)
- Reverted to safe broad rule: -keep class dev.dettmer.simplenotes.** { *; }

Added safety-guards in detectServerDeletions():
- Abort if serverNoteIds is empty (network error, not mass deletion)
- Abort if ALL local notes would be marked deleted (almost certainly a bug)

- Tested: Update from v1.7.2 restores all notes successfully

+
+**R8/ProGuard Obfuscation Fix - Verhindert Datenverlust**
+- 🔧 **KRITISCH:** Falscher ProGuard-Klassenpfad für `Note$Companion$NoteRaw` korrigiert

+  - R8 obfuskierte alle NoteRaw-Felder (id→a, title→b, ...)
+  - Gson konnte JSON nicht mehr parsen → **ALLE Notizen erschienen verschwunden**
+  - Zurück zur sicheren breiten Regel: `-keep class dev.dettmer.simplenotes.** { *; }`
+- 🛡️ Safety-Guards in `detectServerDeletions()` hinzugefügt

+  - Abort wenn ALLE lokalen Notizen als gelöscht erkannt würden
+- ✅ Notizen waren nie wirklich verloren (JSON-Dateien intakt auf Disk + Server)
+- ✅ Downgrade auf v1.7.2 holte alle Notizen zurück

+## [1.7.2] - 2026-02-04
+
+### 🐛 Kritische Fehlerbehebungen
+
+#### JSON/Markdown Timestamp-Synchronisation
+
+**Problem:** Externe Editoren (Obsidian, Typora, VS Code, eigene Editoren) aktualisieren Markdown-Inhalt, aber nicht den YAML `updated:` Timestamp, wodurch die Android-App Änderungen überspringt.
+
+**Lösung:**
+- Server-Datei Änderungszeit (`mtime`) wird jetzt als Source of Truth statt YAML-Timestamp verwendet
+- Inhaltsänderungen werden via Hash-Vergleich erkannt
+- Notizen nach Markdown-Import als `PENDING` markiert → JSON automatisch beim nächsten Sync hochgeladen
+- Behebt Sortierungsprobleme nach externen Bearbeitungen
+
+#### SyncStatus auf Server immer PENDING
+
+**Problem:** Alle JSON-Dateien auf dem Server enthielten `"syncStatus": "PENDING"` auch nach erfolgreichem Sync, was externe Clients verwirrte.
+
+**Lösung:**
+- Status wird jetzt auf `SYNCED` gesetzt **vor** JSON-Serialisierung
+- Server- und lokale Kopien sind jetzt konsistent
+- Externe Web/Tauri-Editoren können Sync-Status korrekt interpretieren
+
+#### Deletion Tracker Race Condition
+
+**Problem:** Batch-Löschungen konnten Lösch-Einträge verlieren durch konkurrierenden Dateizugriff.
+
+**Lösung:**
+- Mutex-basierte Synchronisation für Deletion Tracking
+- Neue `trackDeletionSafe()` Funktion verhindert Race Conditions
+- Garantiert Zombie-Note-Prevention auch bei schnellen Mehrfach-Löschungen
+
+#### ISO8601 Timezone-Parsing
+
+**Problem:** Markdown-Importe schlugen fehl mit Timezone-Offsets wie `+01:00` oder `-05:00`.
+
+**Lösung:**
+- Multi-Format ISO8601 Parser mit Fallback-Kette
+- Unterstützt UTC (Z), Timezone-Offsets (+01:00, +0100) und Millisekunden
+- Kompatibel mit Obsidian, Typora, VS Code Timestamps
+
+### ⚡ Performance-Verbesserungen
+
+#### E-Tag Batch Caching
+
+- E-Tags werden jetzt in einer einzigen Batch-Operation geschrieben statt N einzelner Schreibvorgänge
+- Performance-Gewinn: ~50-100ms pro Sync mit mehreren Notizen
+- Reduzierte Disk-I/O-Operationen
+
+#### Memory Leak Prevention
+
+- `SafeSardineWrapper` implementiert jetzt `Closeable` für explizites Resource-Cleanup
+- HTTP Connection Pool wird nach Sync korrekt aufgeräumt
+- Verhindert Socket-Exhaustion bei häufigen Syncs
+
+### 🔧 Technische Details
+
+- **IMPL_001:** `kotlinx.coroutines.sync.Mutex` für thread-sicheres Deletion Tracking
+- **IMPL_002:** Pattern-basierter ISO8601 Parser mit 8 Format-Varianten
+- **IMPL_003:** Connection Pool Eviction + Dispatcher Shutdown in `close()`
+- **IMPL_004:** Batch `SharedPreferences.Editor` Updates
+- **IMPL_014:** Server `mtime` Parameter in `Note.fromMarkdown()`
+- **IMPL_015:** `syncStatus` vor `toJson()` Aufruf gesetzt

+## [1.7.2] - 2026-02-04
+
+### 🐛 Critical Bug Fixes
+
+#### JSON/Markdown Timestamp Sync
+
+**Problem:** External editors (Obsidian, Typora, VS Code, custom editors) update Markdown content but don't update YAML `updated:` timestamp, causing the Android app to skip changes.
+
+**Solution:**
+- Server file modification time (`mtime`) is now used as source of truth instead of YAML timestamp
+- Content changes detected via hash comparison
+- Notes marked as `PENDING` after Markdown import → JSON automatically re-uploaded on next sync
+- Fixes sorting issues after external edits
+
+#### SyncStatus on Server Always PENDING
+
+**Problem:** All JSON files on server contained `"syncStatus": "PENDING"` even after successful sync, confusing external clients.
+
+**Solution:**
+- Status is now set to `SYNCED` **before** JSON serialization
+- Server and local copies are now consistent
+- External web/Tauri editors can correctly interpret sync state
+
+#### Deletion Tracker Race Condition
+
+**Problem:** Batch deletes could lose deletion records due to concurrent file access.
+
+**Solution:**
+- Mutex-based synchronization for deletion tracking
+- New `trackDeletionSafe()` function prevents race conditions
+- Guarantees zombie note prevention even with rapid deletes
+
+#### ISO8601 Timezone Parsing
+
+**Problem:** Markdown imports failed with timezone offsets like `+01:00` or `-05:00`.
+
+**Solution:**
+- Multi-format ISO8601 parser with fallback chain
+- Supports UTC (Z), timezone offsets (+01:00, +0100), and milliseconds
+- Compatible with Obsidian, Typora, VS Code timestamps
+
+### ⚡ Performance Improvements
+
+#### E-Tag Batch Caching
+
+- E-Tags are now written in single batch operation instead of N individual writes
+- Performance gain: ~50-100ms per sync with multiple notes
+- Reduced disk I/O operations
+
+#### Memory Leak Prevention
+
+- `SafeSardineWrapper` now implements `Closeable` for explicit resource cleanup
+- HTTP connection pool is properly evicted after sync
+- Prevents socket exhaustion during frequent syncs
+
+### 🔧 Technical Details
+
+- **IMPL_001:** `kotlinx.coroutines.sync.Mutex` for thread-safe deletion tracking
+- **IMPL_002:** Pattern-based ISO8601 parser with 8 format variants
+- **IMPL_003:** Connection pool eviction + dispatcher shutdown in `close()`
+- **IMPL_004:** Batch `SharedPreferences.Editor` updates
+- **IMPL_014:** Server `mtime` parameter in `Note.fromMarkdown()`
+- **IMPL_015:** `syncStatus` set before `toJson()` call
