[ralph-loop] CLAUDE_PLUGIN_ROOT not resolving on Windows - inline script fix

[yangzealliator-yz]

Problem

On Windows (with Git Bash), the ${CLAUDE_PLUGIN_ROOT} environment variable is not resolved, causing the ralph-loop plugin to fail:

/usr/bin/bash: line 31: /scripts/setup-ralph-loop.sh: No such file or directory

Environment

• OS: Windows 10/11
• Shell: Git Bash (via Claude Code)
• Plugin: ralph-loop

Root Cause

The ${CLAUDE_PLUGIN_ROOT} variable is not set/exported by Claude Code on Windows.

Proposed Solution

Replace external script call with inline bash script that doesn't depend on ${CLAUDE_PLUGIN_ROOT}.

Benefits:

1. Cross-platform (Windows, macOS, Linux)
2. No external dependencies
3. Self-contained
4. Also fixes ralph-loop fails with 'unbound variable' error - $ARGUMENTS not substituted in ```! block #167 ($ARGUMENTS works in inline scripts)
