fix: Replace hardcoded paths with skill-relative paths in repomix-unmixer

Replace all hardcoded absolute paths (~/.claude/skills/repomix-unmixer/scripts/)
with skill-relative paths (scripts/) to ensure the skill works correctly
regardless of installation method (user skills, project skills, marketplace plugins).

Changes:
- Replace 13 occurrences of hardcoded script paths
- Use skill-relative paths following Anthropic best practices
- Maintain compatibility across all installation contexts

This fixes the error where the skill failed when installed as a marketplace
plugin because it assumed the ~/.claude/skills/ directory structure.
