Add unpackr extension

[kvaishak]

Description

Unpackr intelligently merges multiple ZIP files into a single organized folder with automatic deduplication. Perfect for
Google Takeout archives, photo collections, backups, and any batch of ZIP files.

Key Features

• Universal ZIP Support: Works with Google Takeout, iCloud exports, or any ZIP files
• Smart Deduplication: SHA256-based duplicate detection to skip identical files
• Conflict Resolution: Auto-renames files with same name but different content
• Zip Bomb Protection: Safe Mode enabled by default to detect suspicious archives
• Performance Optimized: Concurrent extraction and memory-efficient streaming (40-60% faster)
• Automatic Error Logging: Creates detailed logs when issues occur
• macOS Compatible: Filters out __MACOSX metadata and .DS_Store files

Problem Solved

When downloading large archives (like Google Photos via Google Takeout), they're split into multiple ZIP files. Manually
merging creates messy, overlapping directories and risks duplicate files or overwriting content. Unpackr automates this
entire process.

Greptile Overview

Greptile Summary

This PR adds a new extension called Unpackr that intelligently merges multiple ZIP files into a single organized folder with automatic deduplication. The extension supports Google Takeout archives and any standard ZIP files, featuring SHA256-based duplicate detection, conflict resolution, zip bomb protection, and performance optimizations through concurrent extraction.

Key Implementation Highlights:

• Robust ZIP processing engine with security features (path traversal protection, zip bomb detection)
• Memory-efficient streaming architecture using generators to handle large file collections
• Smart duplicate detection using SHA256 hashing with file size pre-checks for optimization
• Comprehensive error handling with automatic error logging
• Clean UI with form validation and real-time progress feedback
• Metadata folder with screenshots properly included for this new extension

Minor Issues:

• ESLint configuration uses legacy .eslintrc.json format instead of the recommended eslint.config.js template

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The code demonstrates excellent engineering practices with comprehensive error handling, security considerations (path traversal prevention, zip bomb protection), proper resource cleanup, and thorough validation. The only issue is a minor configuration preference for ESLint format.
• extensions/unpackr/.eslintrc.json should be migrated to eslint.config.js format

Hi 👋

Thanks for your contribution 💪

I have now tested your extension, and I have some feedback ready for you:

• Could you add at least one screenshot of the extension and add them to a folder called metadata - you need to use our tool to get the right padding on the images

I'm looking forward to testing this extension again 🔥

I converted this PR into a draft until it's ready for the review, please press the button Ready for review when it's ready and we'll have a look 😊

Feel free to contact me here or at Slack if you have any questions.

You don't need to manually set preference types as this is autogenerated in raycast-env.d.ts

Thanks for the review @pernielsentikaer. I have updated the screenshots and the manually set preference types.
