On Windows, the daemon stop command was failing with "exit status 1" because `taskkill` without `/F` flag does not work for console processes that do not have windows to receive close messages. Changes: - Use `os.Process.Kill()` which calls Windows `TerminateProcess` API - This is the reliable way to terminate processes on Windows - The graceful RPC shutdown is already attempted before falling back to kill - Updated error messages to be platform-agnostic (removed SIGTERM/SIGKILL) The fix uses Go cross-platform process APIs instead of shelling out to external commands, which is more reliable and portable. Closes #992 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
