docs(skills): organize web-research files in dedicated folder

Addresses TODO(Claude) to specify that all research files should be
organized in a dedicated folder structure.

Changes:
- Added step to create /research_[topic_name]/ folder
- Updated all file paths to use folder structure:
  - /research_plan.md → /research_[topic_name]/research_plan.md
  - /findings_[subtopic].md → /research_[topic_name]/findings_[subtopic].md
  - /research_report.md → /research_[topic_name]/research_report.md
- Updated synthesis step to reference the folder

Benefits:
- Keeps files organized and prevents clutter in working directory
- Makes it easy to manage multiple research projects
- Clear file organization for subagents
