Add install modal for users without Claude Code CLI

Shows a clean modal when Claude Code is not installed, with one-click installation that auto-detects platform (npm if node>=18, otherwise curl/PowerShell). Runs silently in background with progress indicator. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

andrepimenta	683148c4cf	Add install modal for users without Claude Code CLI Shows a clean modal when Claude Code is not installed, with one-click installation that auto-detects platform (npm if node>=18, otherwise curl/PowerShell).

andrepimenta	a156881a08	Migrate permission system from MCP file-based to stdio-based Replace MCP permission server with stdio-based permission flow that communicates directly with Claude CLI via stdin/stdout. This simplifies the architecture and fixes permission expiration issues. Key changes: - Use --permission-prompt-tool stdio and --input-format stream-json - Handle control_request messages for permission prompts - Send control_response via stdin to approve/deny - Check local permissions for auto-approval of pre-approved tools - Only expire pending permissions when VS Code restarts, not panel close 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-12-02 18:07:45 +00:00
