Refine game onboarding for an ML-familiar audience

HF visitors can know basic ML while encountering AI Learns to Drive for the first time. The guide previously reached result delivery without enough context for interpreting a driver or planning the next experiment.

This revision introduces the driving observations and controls, evolutionary search, and the headless lab. It then walks through the existing A01/Formula/CPU baseline, explains fitness versus driving measurements, preserves a checkpoint, and presents evaluation and continuation choices before recipes and batches. Concise links point to the game wiki while retaining this lab's actual defaults and supported behavior.

The persistent Help links now open at the game orientation. Quick start remains compact and closed by default. Existing recipe, batch, freezing, storage, and challenge-reference anchors remain available.

Validation: 8 integrated UI workflow checks passed; 13 unique help anchors and all 18 internal/app-to-help links are valid. First-run values and result labels were checked against the current client. No training job was launched.

Release: merge index.html, help.html, and their RELEASE_MANIFEST.json hashes together. This PR does not change the training client or engine.
