fix: Handle UTF-8 BOM in config loading and build script

Browse Source 
- main.js: Strip UTF-8 BOM when reading config.json
- build-client.bat: Write config.json without BOM using
  [System.Text.UTF8Encoding]::new($false)

PowerShell's -Encoding UTF8 writes BOM by default, which can
cause JSON parsing issues in Node.js.
