fix: pass scope to writeWindsurfBundle and fix skill name casing

- Fix resolve-pr-parallel SKILL.md name from underscores to hyphens
  (must match directory name per Windsurf spec)
- Add scope parameter to TargetHandler.write signature
- Pass resolvedScope through to writer in convert.ts and install.ts
- Windsurf writer uses global_workflows/ for global scope, workflows/
  for workspace scope
