📝 Implementation

Replace ts-node with tsx

• Swapped the TypeScript execution tool from ts-node to tsx for running scripts directly without a build step.
• Removed the now-obsolete ts-node configuration block from the base TypeScript config.
• Bumped the documented required Node version to match the pinned version, since tsx requires a newer Node runtime.

Add husky git hooks

• Introduced husky to manage git hooks, installed automatically on dependency install.
• Added a pre-push hook that runs formatting, linting, and tests, aborting the push if any fail.
• Added a post-merge hook that reinstalls dependencies automatically when the lockfile changed during a merge.

Document the git hooks

• Added a README section explaining the husky setup, how hooks are installed, and what the pre-push and post-merge hooks do.
