Fix CI pipeline build failures by resolving dependencies and typing errors.

- Added missing `hex` crate dependency to `techscript_stdlib` and `techscript_packager`.
- Fixed type signature for `FileOptions` in `techscript_packager` by removing deprecated generic argument.
- Fixed borrow checker compilation error in `techscript_optimizer` by cloning `self.manager.stats`.
