Fix backend (py3.11) CI failure by applying Ruff formatting to precompute module

[Copilot]

What

backend (py3.11) failed in CI because ruff format --check src tests detected formatting drift in src/footyvision/ml/precompute.py. This PR applies the exact formatter-aligned edits required so the job passes without changing runtime behavior.

• Formatting-only correction in precompute.py
  • Reflowed the shortlist list-comprehension slice into Ruff’s preferred wrapped form.
  • Reflowed the models dict-comprehension into Ruff’s preferred multi-line block.

"models": {
    name: _model_meta(model)
    for name, model in zip(TARGETS, (group, role, exact), strict=True)
}

Why

The failing check run (backend (py3.11)) was caused by style non-compliance, not functional defects. Aligning this file with enforced Ruff formatting removes the CI blocker with minimal, non-behavioral change.

Checklist

• ruff check src tests and ruff format --check src tests pass
• pytest passes (tests stay DB-, network- and LLM-free)
• Docs updated (README / docs/) if behaviour or setup changed
• No credentials, .env files or datasets committed
