Add setting to auto-approve computer-use request_access prompt

Feature Request

Problem

When running Claude Code in a non-interactive environment (e.g., a tmux session with --dangerously-skip-permissions and --channels for a Telegram bot), the request_access prompt from the computer-use MCP blocks the entire session indefinitely. There is no way to pre-approve app access, so the bot hangs waiting for user input that will never come.

Current behavior

• --dangerously-skip-permissions bypasses all standard tool permissions ✅
• request_access from computer-use still requires an interactive approval per session ❌
• No setting in settings.json or settings.local.json can skip this prompt
• This makes computer-use completely unusable in any headless/unattended Claude Code setup

Proposed solution

Add a configuration option such as skipComputerUseApproval: true in settings.json or a CLI flag (e.g., --approve-computer-use) that pre-grants access to specified (or all) applications, removing the need for interactive confirmation.

Example config:

{
  "computerUse": {
    "autoApprove": true,
    "allowedApps": ["Google Chrome", "Safari", "Finder"]
  }
}

Use case

Running Claude Code as a 24/7 autonomous agent (via tmux + Telegram plugin) on a dedicated Mac mini. Computer-use is needed for native app automation, but the interactive prompt makes it unusable in headless/unattended mode.

Workaround

Currently forced to use Playwright MCP for web tasks only, losing the ability to interact with native macOS apps.
