Add Storybook for component library documentation and development

[Copilot]

Implements Storybook 8.6.14 to enable isolated component development, visual testing, and auto-generated documentation for the @kacker/ui library.

Changes

Configuration

• Storybook with React-Vite integration
• Mock implementations for Capacitor peer dependencies (@capacitor/app, @capacitor/core, etc.) to enable browser-based development
• Path alias resolution (@/*) matching project TypeScript config
• Tailwind CSS integration

Component Stories (10 components, 54 variants)

• Interactive: Button, Input, Switch, Select, TextArea, Toggle, IconButton, Form
• Layout: Image, Page

Package Updates

• Added Storybook dev dependencies (v8.6.14)
• Added storybook and build-storybook npm scripts
• Removed prepare script to avoid Bun dependency during npm install

Usage

npm install --legacy-peer-deps
npm run storybook  # http://localhost:6006

Technical Notes

The Capacitor mocks in .storybook/mocks/ are essential since the library targets Capacitor mobile apps. They provide minimal implementations returning no-ops and promises, allowing components to render in Storybook without native dependencies.

Stories follow CSF3 format with autodocs enabled for automatic prop documentation. See .storybook/README.md for adding new stories.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• storybook.js.org
  • Triggering command: /usr/local/bin/node node /home/REDACTED/.npm/_npx/16684dbf41d9f438/node_modules/.bin/create-storybook --yes --skip-install (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
