Split a secret into n shares with a reconstruction threshold of threshold.
Uses Shamir's Secret Sharing over GF(p) where p is the Ed25519 group order.
The secret is the constant term of a random polynomial of degree (threshold - 1).
Parameters
secret: string
Hex-encoded 32-byte secret (interpreted as a scalar in GF(p)).
n: number
Total number of shares to generate (must be >= threshold).
threshold: number
Minimum shares required for reconstruction (must be >= 2).
