* fix: sanitize system proxy exceptions to avoid macOS ExceptionsList being dropped

On macOS/Linux the exception list is comma-separated and passed to networksetup. It was only stripped of spaces, so a stray newline or a trailing comma left a malformed/empty entry. macOS configd then silently rejects the whole ExceptionsList (scutil --proxy shows no ExceptionsList), so the bypass never takes effect. Split on ',' with TrimEntries + RemoveEmptyEntries and rejoin; behavior-preserving for well-formed input. Windows path (';') is left unchanged.

Note: not built locally (no .NET SDK on hand); relying on CI.

* Update SysProxyHandler.cs
