Remove hyphens from compound adjectives such as "logged-in", "one-time", "password-protected", "full-height", "multi-file", and "S3-compatible" in comments, test error messages, and UI labels to improve readability and consistency.
Introduces the ability to browse and preview the contents of archive files directly within the web interface.
Changes include:
- Added a new API endpoint `GET /d/{boxID}/archive/{fileID}` to fetch archive listings.
- Implemented on-demand archive listing generation in the backend.
- Updated the frontend preview component to support rendering and navigating archive contents.
- Register a new route `GET /d/{boxID}/scene/{fileID}` to serve video scene previews.
- Implement the `VideoScenesPreview` handler to serve existing previews or generate them on-demand.
- Add helper functions to analyze video frames (e.g., luma calculation to filter out dark frames) and render the final scene thumbnail.
- Update the `fileView` struct to include scene URL and status fields.
Register routes for robots.txt and sitemap.xml, and implement search engine indexing controls to protect user privacy.
Specifically:
- Set `X-Robots-Tag: noindex, nofollow, noarchive` headers on file downloads, thumbnails, and zip generation.
- Configure `Robots: web.RobotsNone` on download and preview pages to prevent indexing of temporary user uploads.
- Add canonical URLs, improved descriptions, and image alt tags to page metadata for better social sharing.
