chore: Add development guidelines documentation for AI Agents (#11243)

Added `AGENTS.md` containing development guidelines, build commands,
code style conventions, and project-specific instructions for easier
onboarding and consistent development practices. Additionally symlink
for `CLAUDE.md` and `windsurf`

+# Chatwoot Development Guidelines
+
+## Build / Test / Lint
+
+- **Setup**: `bundle install && pnpm install`
+- **Run Dev**: `pnpm dev` or `overmind start -f ./Procfile.dev`
+- **Lint JS/Vue**: `pnpm eslint` / `pnpm eslint:fix`
+- **Lint Ruby**: `bundle exec rubocop -a`
+- **Test JS**: `pnpm test` or `pnpm test:watch`
+- **Test Ruby**: `bundle exec rspec spec/path/to/file_spec.rb`
+- **Single Test**: `bundle exec rspec spec/path/to/file_spec.rb:LINE_NUMBER`
+- **Run Project**: `overmind start -f Procfile.dev`
+
+## Code Style
+
+- **Ruby**: Follow RuboCop rules (150 character max line length)
+- **Vue/JS**: Use ESLint (Airbnb base + Vue 3 recommended)
+- **Vue Components**: Use PascalCase
+- **Events**: Use camelCase
+- **I18n**: No bare strings in templates; use i18n
+- **Error Handling**: Use custom exceptions (`lib/custom_exceptions/`)
+- **Models**: Validate presence/uniqueness, add proper indexes
+- **Type Safety**: Use PropTypes in Vue, strong params in Rails
+- **Naming**: Use clear, descriptive names with consistent casing
+- **Vue API**: Always use Composition API with `<script setup>` at the top
+
+## Styling
+
+- **Tailwind Only**:  
+  - Do not write custom CSS  
+  - Do not use scoped CSS  
+  - Do not use inline styles  
+  - Always use Tailwind utility classes  
+- **Colors**: Refer to `tailwind.config.js` for color definitions
+
+## General Guidelines
+
+- MVP focus: Least code change, happy-path only
+- No unnecessary defensive programming
+- Break down complex tasks into small, testable units
+- Iterate after confirmation
+- Avoid writing specs unless explicitly asked
+- Remove dead/unreachable/unused code
+- Don’t write multiple versions or backups for the same logic — pick the best approach and implement it
+- Don't reference Claude in commit messages
+
+## Project-Specific
+
+- **Translations**:
+  - Only update `en.yml` and `en.json`
+  - Other languages are handled by the community
+  - Backend i18n → `en.yml`, Frontend i18n → `en.json`
+- **Frontend**:
+  - Use `components-next/` for message bubbles (the rest is being deprecated)
+
+## Ruby Best Practices
+
+- Use compact `module/class` definitions; avoid nested styles
