Add deployment scripts for blog, links, notes, photos, and projects; implement history squashing and vision processing

- Created `publish-blog.sh`, `publish-links.sh`, `publish-notes.sh`, `publish-photos.sh`, and `publish-projects.sh` for deploying respective content to the VPS.
- Implemented `squash-history.sh` to replace the entire git history with a single commit.
- Added `vision.ts` and `vision.spec.ts` for processing images with AI, including metadata extraction and merging.
- Enhanced error handling and logging in vision processing scripts.
