Add cursor style configuration for input field

Feature Request

Allow users to configure the cursor style in Claude Code's input field.

Current Behavior

The input field cursor is a yellow, non-blinking box that ignores terminal cursor settings (e.g., Alacritty's cursor.style).

Desired Behavior

Add a setting to configure:

• Cursor shape: Block, Beam (I-beam), Underline
• Cursor color: Custom color or inherit from terminal
• Blinking: On/Off

Example Configuration

{
  "cursor": {
    "shape": "beam",
    "color": "#FFFFFF",
    "blinking": true
  }
}

Rationale

Users configure their terminal cursor preferences for consistency and accessibility. Claude Code's input field should respect these preferences or provide its own configuration options.
