select: support number key to jump to option

[gutenye]

Feature Request

Allow pressing number keys (1-9) to jump to and select the corresponding option in the select prompt.

Current Behavior

Users must use arrow keys to navigate options and press Enter to confirm.

Proposed Behavior

When a select prompt has numbered options, pressing a number key (e.g. 1, 2, 3) should immediately jump to and select that option

This is especially useful for short lists (< 10 items) where pressing a single key is much faster than arrow-key navigation.

Example

const answer = await select({
  message: 'Pick a market',
  options: [
    { label: 'Market 1' },
    { label: 'Market 2' },
    { label: 'Market 3' },
  ],
})
// Pressing "2" immediately selects "Market 2"
