c4d03bf1b7 fix(stability): Heap-Leak durch String/JsonDocument-Objekte behoben 
- web_server.cpp: static String _logBuf -> char[6001] im BSS-Segment
  Jeder LOG_I/E/D-Aufruf loeste String-Reallokation aus (~280 Bytes/min Drift)
  Fix: memmove-basierter Ring-Puffer, kein malloc/free mehr
- mqtt_client.cpp: JsonDocument in publishHeartbeat() und _doPublishSession()
  durch snprintf-JSON ersetzt (kein ArduinoJson-Heap-Pool alle 60 s)
- config.h: LOG-Puffer von 200 auf 320 Bytes erhoeht (Truncation fix)
- platformio.ini: CORE_DEBUG_LEVEL wieder auf 1 (war 3 fuer Heap-Diagnose)

a7c6edb458 fix(mqtt): MQTT-Task auf Core 0 auslagern - TLS-Blocking behebt WDT-Crash und Display-Freeze 
- WiFiClientSecure/mbedtls ausschliesslich auf Core 0 initialisiert und verwendet
  (Cross-Core-Heap-Korruption durch mbedtls vermieden)
- xTaskCreatePinnedToCore('mqtt_task', Core 0, 16 KB Stack)
- begin() startet nur Task, kein Netzwerk-Zugriff auf Core 1
- mqttClient.loop() in main.cpp ist No-Op
- publishSession() von Core 1 via volatile-Flags an Core-0-Task uebergeben
- Version: 1.1.0 -> 1.1.1

4dd4ce0620 feat(FR-002): Web Console via HTTP-Polling (/log + /log-data) -- v1.1.0 
- Ring-Buffer _logBuf in web_server.cpp: webLogForward() schreibt auf Core 1
- GET /log-data liefert Puffer als Plain-Text (kein WebSocket, kein Core-Konflikt)
- Browser pollt alle 2 s, Auto-Scroll, dunkles Terminal-Theme
- LOG_I/LOG_E/LOG_D: Timestamp (HH:MM:SS nach NTP, sonst +Xs), webLogForward()
- Alle Serial.* in laser_tracker.cpp, mqtt_client.cpp, web_server.cpp auf LOG_I/LOG_E
- main.cpp: esp_reset_reason() beim Booten loggen (POWER_ON / WATCHDOG / PANIC...)
- telnet_logger.h entfernt (war nur noch Deprecated-Stub)
- Feature-Requests.md: FR-002 abgeschlossen

a97fa0c111 fix(mqtt): session_sum Binaerzahl-Bug behoben 
- String(int, 2) interpretiert 2. Argument als Basis (binaer), nicht Dezimalstellen
  Beispiel: 18 Min -> '10010' (binaer)
- Fix: direkter int-Wert als JSON-Integer (kein serialized/String noetig)
- platformio.ini: Version 1.0.1 -> 1.0.2
- Feature-Requests.md: FR-004 dokumentiert und abgeschlossen

  Automatische Sommer-/Winterzeitumschaltung fuer Deutschland
- mqtt_client.cpp: gmtime() -> localtime(), Z-Suffix entfernt
  session_start_time zeigt Lokalzeit (CET/CEST)
- platformio.ini: Version 1.0.0 -> 1.0.1 (Patch)
- README.md: session_start_time Dokumentation aktualisiert

3827342c0c feat(laser): implement LaserTracker with debounce, gratis time and NVS save 
- Add include/laser_tracker.h: LaserTracker class declaration
  - Software debounce (LASER_DEBOUNCE_MS = 50ms from config.h)
  - Polarity-aware GPIO read (LOW_ACTIVE / HIGH_ACTIVE from settings)
  - Session lifecycle: onSessionStart / onSessionEnd
  - Gratis time countdown, net seconds accumulation
  - Getters: isActive, getTotalMinutes, getSessionSeconds,
    getCountdownRemaining, getLastSessionSeconds, resetTotal

- Add src/laser_tracker.cpp: full implementation
  - readRaw() applies signal polarity
  - loop() handles debounce state machine and edge detection
  - onSessionEnd() saves updated totalMinutes to NVS
  - getTotalMinutes() returns live value (base + current net session)

- Add test_sketches/test_laser_tracker.cpp: interactive test sketch
  - Button on GPIO 4 simulates laser signal
  - BOOT button (GPIO 0, 3s hold) resets total
  - Display: modules 1-3 = total minutes, modules 5-7 = countdown/net

- Add test-laser-tracker env to platformio.ini
- Update src/main.cpp: integrate laserTracker.begin/loop + live display
- Update Implementation-Plan.md: mark Phase 5 tasks 5.1-5.6 complete

4349b37f05 feat(display): implement DisplayManager with raw MD_MAX72XX 
- Add include/display_manager.h: DisplayManager class declaration
  - Two-zone layout: Zone 0 (top, laser time), Zone 1 (bottom, countdown/status)
  - showLaserTime(), showCountdown(), showIdle(), showStatus(), setBrightness()
  - rotateCCW() bitmap transformation for 90 deg physical module rotation
  - charBitmap() for 17-character set (0-9, space, dash, dot, special chars)

- Add src/display_manager.cpp: full implementation
  - Double-init pattern for SPI power stability
  - showLaserTime() format: <10 -> ' x.x', <100 -> 'xx.x', <1000 -> ' xxx', else 'xxxx'
  - showCountdown() right-aligned 4-char format
  - All methods use writeZone() -> writeChar() -> rotateCCW() -> MD_MAX72XX

- Add test_sketches/test_display_manager.cpp: 6-step verification test
  - allLedsOn/Off, showLaserTime (12 boundary values), showCountdown 5->0
  - showIdle, showStatus (Err/AP/WiFi/oF), live simulation loop

- Update platformio.ini: add test-display-mgr environment
- Update src/main.cpp: integrate display.begin/showIdle/update
- Update Implementation-Plan.md: mark Phase 4 tasks 4.1-4.3 complete

Tested on hardware: all 6 test steps passed
