README: list the handoff-needs-smoke-test hook

[EdbertChan]

Summary

The main readme has a table listing every safety hook and what it does.

This adds the row for the new hook lower in this stack. That hook checks that a script handed to a person has been run first.

The PR checker counts the main readme as documentation, a separate kind of change, so the row lives in its own PR.

Review Claim

Approve one new row in the main readme's hook table, for the hook added at the bottom of this stack.

Safety Invariant

Only one table row is added. No code changes.

Slice Rationale

The row describes a hook added lower in this stack, so this lands after it. Keeping it separate lets the hook PR hold one kind of change.

Non-goals

• Does not change the hook, its own guide, or its inventory row.
• Does not list the login-shell hook; that hook is not in this stack.
