A new setting wired the way every other setting in the project is wired.

## Goal

Add a configuration flag following the project's existing configuration pattern.

## Acceptance criteria

- The flag is validated at startup rather than at first use
- Each branch has a test
- The default is documented alongside the other settings
- An invalid value fails loudly at boot

## What lands as proof

Tests for both branches plus a boot failure on an invalid value, so a typo cannot ship silently.

## Questions

### What does the agent actually change?

The ticket is scoped to one outcome: add a configuration flag following the project's existing configuration pattern. Work that serves that outcome is in scope, and anything outside it is left for a separate ticket, so the pull request stays reviewable.

### How do I know the work is done?

The pull request carries the evidence, not only the diff. Here that means a test per branch, the default recorded in the docs, so a reviewer can confirm the result without reproducing the work locally.

### How much oversight does this need?

None is required before the run starts. Every claim this ticket makes can be checked by machine, so the agent works straight through and a person reviews the finished pull request like any other.
