HYPERFLEET-991 - feat: add PR risk scoring presubmit job

Add a new step-registry ref `hyperfleet-risk-scorer` that computes a
deterministic risk score for PRs based on diff size, sensitive path
changes, and test coverage. The job applies a risk/low, risk/medium,
or risk/high GitHub label and posts a score breakdown comment.

The job is configured as optional (never blocks merge) and uses the
`hyperfleet-ci-bot` GitHub App for API access.

Enabled for: hyperfleet-adapter, hyperfleet-api, hyperfleet-broker,
hyperfleet-sentinel.
