Integrate Farcaster Usernames into Delegation Workflow

[b3nedictvs]

Is your feature request related to a problem? Please describe.
Currently, connecting external wallets to miniapps is unreliable, which makes it harder for Farcaster-native users to delegate and participate in governance. Given that this is a Farcaster-native community, relying on wallet connections creates friction.

Describe the solution you'd like
Allow users to type in their Farcaster username to detect their primary Farcaster wallet and delegate to themselves. This would provide a seamless way for users to participate in governance directly through the miniapp.

Describe alternatives you've considered

• Relying on external wallet connections (currently not working well in miniapps).
• Manual entry of wallet addresses (less user-friendly and error-prone).

Additional context
Goal: Make delegation and governance participation super simple for Farcaster users by integrating natively with their usernames.
