[Feature Request] Add customizable color option for user input messages in CLI

Bug Description
Feature Request: Customizable color for user input messages in the CLI

Currently, in the Claude Code CLI, user messages and Claude's responses use the same text color, making it hard to visually scan long conversations.

Request: Add a setting (e.g., in settings.json) to customize the color of the user's input text — for example, displaying it in blue — so it's immediately distinguishable from Claude's output without relying
on terminal-level theming.

Expected behavior: A config option like "userMessageColor": "blue" that applies ANSI color to the user's turn in the conversation display.
