v1.6.0: Switch to user-logon task, migrate API to tsgwp00525 FQDN

- Install-ScheduledTask.ps1: run at user logon with visible UI (was startup
  with no UI), hardcode install path to C:\eDNC-Fix
- Migrate ShopDB API URL from http://geitshopdb/api.asp to
  https://tsgwp00525.rd.ds.ge.com/shopdb/api.asp in code and docs
- eDNC-SpecialCharFix.ps1: ~250 line rework (see diff)

 .NOTES
     Author: GE Aerospace - Rutland
-    Version: 1.5.1
+    Version: 1.6.0
     Date: 2025-12-12
 
+    v1.6.0 - Auto-update loop fix:
+    - Fixed update loop when running as standard user (can't write to C:\eDNC-Fix)
+    - Added -ErrorAction Stop to Copy-Item to properly catch permission errors
+    - Verify version.ini was actually updated before restarting
+    - Disable further update checks after failure to prevent retry loop
+
+    v1.5.9 - Auto-update debugging:
+    - Check for updates immediately at startup (not just every 5 min)
+    - Added diagnostic output for update checks (shows source path, version comparison)
+    - Shows message when periodic update check runs
+
+    v1.5.8 - Update logging and event handler fix:
+    - Log "updated" event to API when auto-update occurs
+    - Fixed event handler to use synchronized hashtable instead of $script: variables
+      (event handlers run in separate runspaces where $script: is not accessible)
+
+    v1.5.7 - Improved file detection:
+    - Added Renamed event handler (some apps write temp then rename)
+    - Increased internal buffer to 64KB to prevent missed events
+    - Added debug logging for watcher configuration
+
+    v1.5.6 - Added explicit NotifyFilter for better file detection
+
+    v1.5.5 - Scheduled task now runs at logon with visible UI (for debugging)
+
+    v1.5.4 - Updated API URL to production server (tsgwp00525.rd.ds.ge.com)
+
+    v1.5.3 - PowerShell 5.1 compatibility fix:
+    - Replaced Join-String (PS 6+) with -join operator (PS 5.1 compatible)
+
+    v1.5.2 - Headless mode support:
+    - Detects when running without console (scheduled task with -WindowStyle Hidden)
+    - Logs to %TEMP%\eDNC-SpecialCharFix.log instead of console
+    - Fixed Install-ScheduledTask.ps1 to always use C:\eDNC-Fix path
+    - Added 60-second startup delay for scheduled task
+
     v1.5.1 - Startup warning if PC not registered in ShopDB
     v1.5.0 - API logging:
     - Logs events (started, cleaned, ok, failed, error, stopped) to ShopDB API
