chore(release): v1.7.2 - Critical Bugfixes & Performance Improvements

CRITICAL BUGFIXES:
- IMPL_014: JSON/Markdown Timestamp Sync - Server mtime source of truth
- IMPL_015: SyncStatus PENDING Fix - Set before JSON serialization
- IMPL_001: Deletion Tracker Race Condition - Mutex-based sync
- IMPL_002: ISO8601 Timezone Parsing - Multi-format support
- IMPL_003: Memory Leak Prevention - SafeSardine Closeable
- IMPL_004: E-Tag Batch Caching - ~50-100ms performance gain

FEATURES:
- Auto-updating timestamps in UI (every 30s)
- Performance optimizations for Staggered Grid scrolling

BUILD:
- versionCode: 19
- versionName: 1.7.2

This release prepares for a new cross-platform Markdown editor
(Web, Desktop Windows + Linux, Mobile) with proper JSON ↔ Markdown synchronization
and resolves critical sync issues for external editor integration.

## [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
