Mint personal tokens

Human avatars accrue issuance continuously (capped at roughly 24 CRC per day) and expose helpers under avatar.personalToken:

const mintable = await avatar.personalToken.getMintableAmount();
console.log(`Mintable CRC: ${mintable.amount}`);

if (mintable.amount > 0n) {
  const receipt = await avatar.personalToken.mint();
  console.log('Mint transaction hash:', receipt.hash);
}

• getMintableAmount() returns the currently claimable amount plus the accrual window.

• mint() calls hubV2.personalMint() via the configured runner.
