feat(lab): add `three_number` test suite and solution

- Implemented the `three_number` Python solution file.
- Integrated `three_number` into the `TestSuiteType` enum with dynamic lookup using `strum`.
- Defined test suite initialization, runner, and judge functions for `three_number`.
- Updated `Cargo.toml` to include `strum` and `strum_macros` dependencies.
- Enhanced utility functions with improved number extraction using `num-traits`.

This commit adds support for evaluating the `three_number` problem and enhances related infrastructure.

Refactor artifact handling in build workflow

Reorganized artifact handling to improve release structure. Artifacts are now copied to a dedicated `release` directory with platform-specific naming. Updated the release action to upload files from `release/` instead of `artifacts/`.
