Release v0.2.2

MigChat CLI v0.2.2

Critical Bug Fixes

🔒 Fixed MAC Verification Failure (Issue with all encrypted messages)

• Fixed critical bug where encryption used a random nonce but decryption used a zero nonce
• This caused "MAC verification failed" errors even with newly created accounts
• Now properly prepends nonce (12 bytes) to ciphertext and extracts it during decryption
• MAC computation now includes nonce+ciphertext consistently on both sides
• All users should upgrade immediately - this fixes message decryption for all encrypted conversations

🪟 Fixed Windows PowerShell Installer

• Simplified color output functions for better compatibility when piped through `iex`
• Replaced box-drawing characters with ASCII for better terminal compatibility
• Added detailed error output with stack traces for debugging
• Added `-UseBasicParsing` to API calls for better compatibility
• Installer should now work reliably in all PowerShell environments

Breaking Changes

⚠️ Important: Due to the nonce handling fix, messages encrypted with v0.2.1 or earlier cannot be decrypted with v0.2.2. However, new sessions will work correctly. If you have existing encrypted conversations, both parties should upgrade to v0.2.2 and start new conversations.
