docs(queue): align README to the @bymax-one lib standard

[msalvatti]

Brings the README to the exact same standard as @bymax-one/nest-auth, nest-logger, and nest-cache:

• Centered header — NestJS badge image, <h1 align=center>, tagline (<strong> + <sub> feature list ending in Zero Runtime Dependencies).
• Same 9 badge tags — npm version, npm downloads, CI status, coverage 100%, mutation 98.99% (→ mutation results), OpenSSF Scorecard (scorecard.dev), license, TypeScript strict, Node.js 24+. (Replaces the old codecov / SLSA / securityscorecards.dev badges.)
• Nav row — GitHub · Issues · Quick Start · API Reference · Example App.
• Emoji section headings matching the sibling convention (✨ Overview, 🔥 Features, 🚀 Quick Start, 📖 API Reference, 📦 Subpath Exports, 🤔 Why over, 🧱 Tech Stack, 🧪 Testing & Quality, 🚫 What This Library Does NOT Do, 🤝 Contributing, 🔒 Security Policy, 📄 License) + centered "Built with ❤️ by Bymax One" footer.
• Added Overview / Why, Features, Tech Stack, Testing & Quality, and Security Policy sections; all existing queue-specific content (Modes, API, decorators, Job Schedulers, dedup/telemetry, graceful shutdown, troubleshooting) is preserved.
• Aligned the security contact to support@bymax.one in both README and SECURITY.md (matches all sibling libs).

Docs-only; no source or CI changes.

README.md:564

• "phased roadmap" is a forward-looking framing that can become outdated in the README. If this link is meant as stable contributor guidance, consider describing it in timeless terms (principles/standards) rather than a roadmap.

Pull requests are welcome. Please open an issue first for significant changes.

- Read [`docs/technical_specification.md`](docs/technical_specification.md) for architecture decisions.
- Read [`docs/development_plan.md`](docs/development_plan.md) for the phased roadmap.
- Run the full gate: `pnpm typecheck && pnpm lint && pnpm test:cov:all && pnpm build && pnpm size`

README.md:545

• This bullet is time-bound ("v6 promotion is planned once…") and is likely to go stale; most of the README is written as timeless guarantees. Consider rephrasing to a present-tense statement about current support and pointing readers to the version policy without promising when v6 will land.

## 🚫 What This Library Does NOT Do

- **NestJS only** — does not work with plain Express, standalone Fastify, or other frameworks.
- **Node.js only** — Deno and Bun are not supported.
- **BullMQ `^5.16` (0.1.x floor)** — v6 promotion is planned once the E2E suite is
