    🌟 What's New in v1.1.4
    1. ⚡ Native Swagger UI In-Page Enhancements
    Direct {{variable}} Autocomplete & Live Resolution: Type {{ in Swagger request bodies, query parameters, or path parameters to get live autocomplete suggestions. Placeholders are dynamically resolved during execution and synchronized directly to Swagger's Redux state.
    Top Pinned Operations Tray: Star any endpoint to pin it into a convenient top tray above Swagger's operations for fast 1-click navigation.
    Paste cURL to Auto-Fill: Paste raw cURL commands directly into Swagger UI to automatically find the endpoint, fill headers, path parameters, query parameters, and body payloads.
    Global Debug Headers Injector: Inject persistent custom HTTP headers (e.g., X-Tenant-ID, X-Trace-Id, custom auth) globally across all native Swagger UI requests.
    Multi-Account Switcher & Live Auth Badge: Switch between saved user/service credentials directly beside Swagger's native "Authorize" button, with automatic token refresh on 401/expiration.
    Multi-Language Code Snippet Generator: 1-click copy any Swagger operation as cURL, JavaScript Fetch, Axios, PowerShell, or Python.
    Collapsible Response JSON Tree Viewer & Search: Interactive collapsible tree viewer for large JSON responses with real-time text matching, highlight markers, and 1-click export to JSON or RFC 4180 CSV.
    1-Click Realistic Mock Data: Auto-populate complex request bodies with realistic, schema-aware mock values based on OpenAPI property names and types.
    Smart JSON Formatter with Auto-Repair: Clean, format, and automatically fix common JSON syntax errors (trailing commas, unquoted keys, single quotes) with dynamic error indicators.
    1-Click Quick Payload History: Re-fill the last sent request body for any operation with a single click.
    Save Response to Variable: Click any JSON response property to immediately extract and save it into active environment variables.
    2. 🔄 Multi-Step Scenario Workflow Runner
    Chained End-to-End API Workflows: Chain multiple endpoints together (e.g. POST /login ➔ extract token ➔ POST /orders ➔ GET /orders/{id}).
    Real-Time Step Streaming & Diagnostics: Run workflows with live progress indicators, per-step timing benchmarks, and payload inspectors.
    Execution Controls: Configurable step failure modes (Stop immediately, Continue on error), step reordering, and full workflow suite JSON export/import.
    3. 🔒 Security, Backup & Theming
    AES-GCM Encrypted Backups: Passphrase-protect your exported backups using AES-256-GCM + PBKDF2 Web Crypto encryption.
    Automatic Credential Sanitization: Cleartext passwords in login templates are automatically redacted before export to prevent credential leakage.
    Dynamic Theme Syncing: Automatically adapts colors to Swagger UI light and dark themes (including FastAPI /docs, drf-yasg, and custom dark mode stylesheets).
    Configurable Feature Toggles: Enable or disable specific in-page Swagger enhancements anytime in the extension's Settings tab.
