Add bun feedback command for user feedback submission
Implements a new `bun feedback` subcommand that allows users to send feedback to the Bun team. Features: - Accepts feedback via positional arguments or piped input - Collects system information (OS, CPU architecture, Bun version) - Manages user email with persistence and git config fallback - Sends feedback to https://bun.com/api/v1/feedback - Supports BUN_FEEDBACK_URL environment variable for testing - Shows progress indicator during submission - Comprehensive test coverage The command is implemented as an embedded TypeScript eval script for faster builds, avoiding the module system overhead. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
