Request: Implement Shamir Secret Sharing for Enhanced Seed Security

Hi Jade team,

I’d like to suggest adding Shamir Secret Sharing to Jade. It’s a great way to split a seed phrase into something like a 2-of-3 or 3-of-5 scheme without moving funds.

Why it’s awesome:
- Security boost: Splitting the seed across multiple shares stored separately means one getting stolen isn’t enough to lose your funds.
- Privacy win: Distributing shares discreetly adds a layer of privacy to seed management.
- Recovery safety: If a share is lost, you can still recover with the others as long as you hit the threshold.

Other wallets like Trezor, BlueWallet, Sparrow, and Electrum already support it, showing there’s demand. SLIP-39 is a defined standard, so implementation should be straightforward and compatible with those wallets.

This would be a killer feature for Bitcoiners looking to level up their security setup as needed.

Thanks for considering it!
