Update dependencies and migrate to @rollup/plugin-terser

[Armruo]

Hi, thanks for providing this excellent token vesting tool, it has been incredibly helpful for me.
I'd like to contribute by updating some dependencies to their latest stable versions.

Description

This PR updates several dependencies to their latest stable versions and replaces the deprecated rollup-plugin-terser with the officially recommended @rollup/plugin-terser.

Why migrate to @rollup/plugin-terser

According to the official Rollup documentation and repositories:

1. rollup-plugin-terser is now archived and no longer maintained (see: https://github.com/TrySound/rollup-plugin-terser)
2. @rollup/plugin-terser is the official replacement (see: https://github.com/rollup/plugins/tree/master/packages/terser)
3. Better compatibility with Rollup v3+ and modern JavaScript features
4. Maintained by the Rollup core team ensuring long-term support
