[Feature Request] Add Windows-compatible alternative to shell script Ralph loop plugin

Bug Description

The ralph-loop plugin's Stop hook uses a bash shell script (stop-hook.sh) that fails on Windows systems when the user profile path contains spaces.

Root Cause

The hook is defined in hooks/hooks.json as:
{
"type": "command",
"command": "${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh"
}

When ${CLAUDE_PLUGIN_ROOT} expands to a Windows path with spaces (e.g., C:\Users\Sathwik Kuncham\.claude\plugins\...), bash incorrectly parses the path due to:

1. Backslashes being stripped or misinterpreted
2. Spaces causing word-splitting

Error Message

Stop hook error: Failed with non-blocking status code: /bin/bash: C:UsersSathwik: No such file or directory

Additional Windows Compatibility Issues in stop-hook.sh

• Uses #!/bin/bash shebang (Unix-only)
• Uses Unix path separators (/) for file paths
• Depends on Unix utilities: sed, awk, grep, perl, jq
