feat: add custom output directory support to vf-eval

[ericlau98]

Summary

• Add optional path argument to -s/--save-results flag in vf-eval
• When path provided, results save to custom location instead of default ./outputs
• Adds output_dir field to EvalConfig and updates path_utils.py

Usage

vf-eval gsm8k -s                 # save to default location
vf-eval gsm8k -s /custom/path    # save to custom location

---

Note

Enables saving eval outputs to a custom directory and adds a new RL config.

• CLI: --save-results/-s now optionally accepts a PATH; without a path it behaves as a boolean flag. The chosen path is propagated as output_dir.
• Plumb output_dir through the stack: add output_dir to EvalConfig, pass it from verifiers/scripts/eval.py, and make get_eval_results_path in verifiers/utils/path_utils.py honor it while preserving default ./outputs behavior.
• Add configs/vf-rl/math-python.toml with env.id and run_name set to math-python.

Config file references wrong environment ID

The math-python.toml configuration file sets id = "primeintellect/wiki-search" and run_name = "wiki-search", but it should reference the math-python environment instead. The environments/math_python/ directory exists with proper metadata indicating the environment ID is math-python. This appears to be a copy-paste error from another config file, causing the math-python config to load an entirely different environment when used.
