feat: remove v2 logic & support v3

[wingkwong]

📝 Description

This PR is to adopt HeroUI v3 and remove unused logic from v2.

Summary:

• Simplified all CLI commands (add, remove, upgrade, list, env, doctor) to only manage @heroui/react and @heroui/styles instead of individual component packages
• Removed components.json registry and all component-level tracking logic
• Removed tailwind config, App.tsx, and pnpm checks from doctor command
• Added peer dependency detection to add and upgrade actions — missing or outdated peer deps are displayed and installed/upgraded automatically
• Added confirmation prompts before add, remove, and upgrade actions
• add action shows packages and peer dependencies in separate tables before installation
• upgrade action displays upgradable packages and peer dependencies in boxed tables
• remove action shows installed versions only (no "new version" display)
• doctor action reports missing peer dependencies with the original version range from peerDependencies
• getPackageInfo now handles directory paths (appends /package.json) and exits gracefully on read errors
• Removed dead code: fix.ts, setup.ts, beta.ts, component.ts, plugin-copy.ts, HeroUI Chat codebase helpers, laravel/remix template logic, and outdated screenshots
• Consolidated @heroui/react and @heroui/styles into shared HEROUI_PACKAGES constant
• Bumped dependencies
• Updated README to reflect all command changes
