[WIP] Enhance zero_day_guard_eval.py with OneClassSVM and optimization

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

I want to enhance the zero_day_guard_eval.py script.

Currently, it uses IsolationForest and LocalOutlierFactor with hardcoded weights (0.6 and 0.4).

I want to improve this by:

1. Adding OneClassSVM from sklearn.svm to the ensemble.
2. Adding a hyperparameter optimization step using GridSearchCV from sklearn.model_selection to find the best weights for the three models (iso, lof, svm).

The synthetic data generation and the rest of the script (AUC calculation, threshold finding, plotting, saving config) should be adapted to use the new optimized ensemble. The new config should include the optimized weights.

The following is the prior conversation context from the user's chat exploration (may be truncated):

Assistant: I've reviewed the repository and it looks like the ROADMAP.md indicates that the "Sponsorship Integration" is complete, which includes adding a "Buy Me A Coffee" QR code to the README.md.

However, the README.md file doesn't seem to have this QR code or a "Funding" section yet. I can add this for you. I'll create a "Funding & Sponsors" section and include the QR code and a link to your "Buy Me A Coffee" page.

I'll create a new pull request with this change. Would you like me to proceed?

User: yes

Assistant: Got it. I will create a pull request to add the funding section to your README.md.

Assistant: OK. I'm waiting for you to approve my plan. Once you do, I'll proceed with creating the pull request.
