fix: image watcher now uses relative path for subdirectory images

- Added relativePath field to ImageDetectedEvent
- Compute relative path from working directory in image-watcher
- Use relativePath in frontend URL (fixes 'Failed to load image' for subdirs)
- Minor CLAUDE.md improvements

chore: bump version to 0.1461
