v0.0.5 - ci: 👷 Update Rust toolchain to nightly in format workflow (#12)

🌟 Summary

v0.0.5 is a tooling-focused release 🎛️ that standardizes the Rust toolchain on nightly, tightens formatting/linting in CI, and refreshes crate metadata—making development smoother and more consistent for contributors.

---

📊 Key Changes

• 🛠️ Rust toolchain upgraded to nightly everywhere

  • CI formatting workflow now uses dtolnay/rust-toolchain@nightly instead of @stable.
  • CI publish workflow also switched to @nightly and explicitly installs:
    • rustfmt for formatting checks
    • clippy for linting

• 📦 Crate version bump

  • Cargo.toml version updated from 0.0.4 ➜ 0.0.5.

• 📚 Improved crate metadata

  • Added a documentation link in Cargo.toml pointing to Ultralytics Docs.

• 🧩 Project-wide toolchain configuration

  • New rust-toolchain.toml file added to define a consistent nightly toolchain, components, and targets for all developers:
    • Channel: nightly
    • Components: rustfmt, clippy, rust-src, rust-analyzer
    • Targets: major Linux, macOS (Intel & Apple Silicon), and Windows architectures.

• ✨ Enhanced formatting config

  • rustfmt.toml now enables unstable_features = true to support nightly-only formatting options.

---

🎯 Purpose & Impact

• ✅ Consistent formatting & linting across environments
  Ensures cargo fmt and cargo clippy behave the same for everyone—locally and in CI—reducing “works on my machine” issues and noisy diffs.

• 🚀 Enables advanced nightly-only formatting features
  By opting into nightly and unstable rustfmt features, the project can use more powerful, stricter, or more expressive formatting rules.

• 🧱 Stronger, more predictable CI
  CI now explicitly installs and runs rustfmt and clippy, catching style and correctness issues earlier, before they hit main branches.

• 🌐 Better discoverability & documentation linkage
  Adding the docs URL to Cargo.toml makes it easier for users to jump from the crate to Ultralytics documentation via crates.io or IDE integrations.

• 📌 Patch release reflecting tooling upgrades
  Version 0.0.5 cleanly marks this as a tooling/infra-focused update—no breaking API changes, but a more polished developer experience.
