/**
 * Init's answer to "where is this repository hosted?" (gitlab-and-plain-git/AC-7 … AC-13).
 *
 * Pure except for the prompt, so every branch is testable with a prompter double. The order
 * is flag, then a valid saved value, then detection from `origin`; only when all three are
 * silent is anyone asked — and a non-interactive init writes nothing at all, which reads as
 * `github`, exactly what the project did before the key existed.
 *
 * Detection runs in every init mode (design D5): it is one local `git` call, and writing what
 * it finds is what makes a GitLab project right after a plain `aidlc init --non-interactive`.
 *
