Address code review feedback

Critical fixes:
1. using_swc? already properly parses YAML (no changes needed)
2. Make precompile hook cross-platform:
   - Replace Unix-specific `command -v` with Ruby's system() array form
   - Use File::NULL for cross-platform output redirection
   - Use array form of system() calls for better reliability
3. Fix fragile config detection in precompile hook:
   - Use regex to match only actual config assignments
   - Ignore comments and strings containing config names
4. Remove development documentation files:
   - ISSUE_ANALYSIS.md
   - PR_REVIEW_RESPONSE.md
   - package_json_issue_comment.md
5. Fix Rake task management:
   - Remove Rake::Task.clear (was clearing ALL tasks, not just ours)
   - Add task.reenable to support multiple invocations

These changes improve cross-platform compatibility (Windows support),
prevent false positives in config detection, and fix rake task issues.
