Release v0.7.5

🔧 chore: enhance release task with compression and checksum generation

Modify the release task in Taskfile.yml to:
- Compress binaries for different platforms (zip for Windows, tar.gz for others)
- Generate SHA256 checksums for each compressed artifact
- Clean up intermediate binary files after compression

This change improves the release process by providing compressed, easily distributable artifacts with integrity verification.
