refactor(skill): rename components for semantic clarity

Rename components and reorganize directory structure:
- skill-doc-editor.tsx → file-content-panel.tsx (handles edit/preview/download)
- editor-area.tsx → content-area.tsx
- editor-body.tsx → content-body.tsx
- editor-tabs.tsx → file-tabs.tsx
- editor-tab-item.tsx → file-tab-item.tsx

Create viewer/ directory for non-editor components:
- Move media-file-preview.tsx from editor/ to viewer/
- Move unsupported-file-download.tsx from editor/ to viewer/

This clarifies the distinction between:
- editor/: actual file editors (code, markdown)
- viewer/: preview and download components (media, unsupported files)
