Feat/sovereign mohawk baseline starter

[rwilliamspbg-ops]

Summary
This PR adds an initial baseline scaffold under baselines/sovereign_mohawk inspired by the contribution proposal discussed in issue planning.

Included in this first commit set:

New baseline package layout and Flower app wiring
Runnable ServerApp + ClientApp + dataset/model scaffold
Baseline README with environment setup, run commands, and smoke-test expectations
Optional verification hooks (enable-verification-hooks) that run lightweight checks on aggregated tensors and produce a report artifact
What this enables
A contributor-friendly starting point for iterating toward a full verifiable aggregation baseline
Reproducible baseline setup following Flower baseline conventions
Early operational evidence via verification_report.json
Verification done
Updated files pass editor diagnostics
Baseline includes explicit lint/test commands:
./dev/format-baseline.sh sovereign_mohawk
./dev/test-baseline.sh sovereign_mohawk
Contribution Compliance

Pull request overview

Adds a new Flower baseline scaffold under baselines/sovereign_mohawk/ (based on the baseline template) and introduces optional “verification hooks” to run lightweight numerical checks on aggregated tensors and emit a verification_report.json artifact.

Changes:

• New baseline package (ServerApp/ClientApp) wired via [tool.flwr.app.components] in pyproject.toml
• CIFAR10 dataset loader + small CNN model scaffold (baseline-template parity)
• Optional verification/reporting utilities invoked on the server after aggregation
