feat(builder): lock ability to default builder code and auto-approve

[Ansonhkg]

WHAT

• add a single DEFAULT_BUILDER constant (address + 0.05% fee) and force both spot/perp helpers to always attach it to every Hyperliquid order
• remove all builder-related inputs from the ability schemas/types and stop passing overrides through the executor
• introduce an approveBuilder helper/action that simply runs approveBuilderFee for the default builder so users can enable fee sharing without supplying params

USAGE

// BEFORE
await executeSpotOrder({
  params: {
    symbol: 'HYPE/USDC',
    price: '0.25',
    size: '100',
    isBuy: true,
    orderType: { type: 'limit', tif: 'Gtc' },
  },
});


// AFTER
await executeSpotOrder({
  params: {
    symbol: 'HYPE/USDC',
    price: '0.25',
    size: '100',
    isBuy: true,
    orderType: { type: 'limit', tif: 'Gtc' },
    builder: { address: '0xCustom', fee: 100 },
  },
});
