feat: folder-wide media metadata stripping + auto-detect

[I7T5]

Hi Natalie! I was trying to find something that will strip all my metadata from the media on my personal website, and I found your extension. Thanks for creating and open-sourcing it! I asked Claude Code to add a bulk strip command in the command palette, as well as an auto-strip option for folders/repos with remote origin. Hope it's running and helpful. Let me know if anything's not working.

What & why

Media files (images, GIFs, videos) carry metadata — EXIF GPS, device serials, timestamps, author names — that silently leaks when a repo is pushed to a public remote. This builds on Meta-Scraper's single-file image cleaning to make it a repo-oriented privacy tool.

Changes

• New command: "Strip Metadata from All Media in Folder" (Command Palette + right-click on a folder). Batch-strips the workspace/folder with a cancellable progress bar, sharing a single ExifTool process and gracefully skipping formats exiftool can't write.
• Automatic detection of newly added media via a FileSystemWatcher, gated to Git repositories that have a remote origin (the "made public online" case). Behavior is configurable — strip / ask / do nothing.
• First-run prompt (per workspace) the first time the folder command runs: offers to enable auto-detection and pick its behavior, writing the new settings.
• New settings: metascraper.autoDetectNewMedia (checkbox) and metascraper.onNewMedia (strip / ask / do nothing).
• Refactored the exiftool strip core into a shared stripFile() used by the folder, single-file, and watcher paths (in-place via -overwrite_original).
• Broadened supported media to GIFs, more image formats (.tif/.heic/.heif/.bmp), and MP4/MOV/M4V video.

Verification

• npm run lint — clean (one pre-existing warning in test-image/example-usage.js, untouched).
• npm test — passes; logs confirm the extension activates in a real Extension Host.
• Automated strip proof: injected GPS/camera/author/software/timestamp EXIF into a JPEG, ran the exact stripFile operation, asserted all 11 sensitive tags removed and the image stayed a valid JPEG.
