chore: migrate to Rstack CLI

[chenjiahan]

Summary

Centralizes testing, formatting, and Git hooks with Rstack CLI 0.7.2, replacing the separate Rstest, Prettier, Husky, and lint-staged setups. The resolver and compatibility suites run as separate test projects, with Rust/TOML checks handled by rs staged. CI moves to Node.js 22/24 to meet Rstack's runtime requirements.

🟡 Changes recommended

There are a few workflow robustness issues to address (notably Node version pinning for Rstack’s engine constraints, and ensuring formatting/hook behavior matches the previous ignore/hook expectations).

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Migrates the repository’s dev workflow (tests, formatting, and Git hooks) from the standalone Rstest/Prettier/Husky/lint-staged setup to a unified Rstack CLI (rs) configuration, and updates CI to run on newer Node versions.

Changes:

• Replaced Rstest configs and test imports with Rstack test projects defined in rstack.config.mts.
• Switched formatting + staged-file checks from Prettier/lint-staged to rs fmt / rs staged, and replaced Husky with rs hooks.
• Updated CI and the pnpm setup action to align with the new Node/runtime expectations.
