fix: use direct HTTPS URL for libsignal dependency

The root cause was simple: Yarn converts git+https:// to SSH.

Solution: Change package.json to use direct HTTPS URL
- Before: "git+https://github.com/whiskeysockets/libsignal-node"
- After: "https://github.com/whiskeysockets/libsignal-node.git"

This eliminates SSH conversion completely and works with all package managers.

Also simplified workflow by removing unnecessary workarounds:
- Removed temporary package.json patching step
- Removed retry logic
- Restored simple 'yarn install --immutable'

Clean, permanent solution. 🎯
