chore: Migrate pre-commit tooling to Lefthook and update CI/Node version (#66)

This pull request updates the CI workflow and replaces the pre-commit
tooling from Husky and lint-staged to Lefthook, simplifying
configuration and improving compatibility with newer Node.js versions.
It also updates the minimum required Node.js version and makes some
minor package metadata changes.

**CI workflow and Node.js version updates:**

* Updated `.github/workflows/ci.yml` to use Node.js v24, and upgraded
the actions for checkout, setup-node, and cache to their latest major
versions for improved compatibility and performance.
* Increased the minimum required Node.js version in `package.json` from
22 to 24.

**Pre-commit tooling migration:**

* Removed Husky and lint-staged configuration and dependencies from
`package.json`, `.husky/pre-commit`, and `.husky/.gitignore`.

* Added Lefthook configuration in `lefthook.yml` to run Prettier and
ESLint in parallel on staged TypeScript files during pre-commit.
* Added Lefthook as a dev dependency in `package.json`.

**Minor metadata change:**

* Changed the package version in `package.json` from `1.0.0` to `0.0.1`
and set `"private": true`.
