v0.2.0

• Friends & direct messages. Add friends, accept/decline requests, block/unblock, and DM anyone you're friends with — scoped to the instance you're on.
• Two-factor authentication. Secure your account with an authenticator app (TOTP — Google Authenticator, Authy, etc.) or a security key / platform authenticator (YubiKey, Touch ID, Windows Hello), plus one-time backup codes for account recovery.
• Fixed a crash when logging in with a backup code.
• Fixed a layout bug where the app's four main panels could grow past their intended size instead of scrolling.
