/**
 * Parse a version string for ordering.
 *
 * Registry versions are validated as `x.y.z` by the backend, but the resolver
 * also orders versions written by hand in `mops.toml`, so coerce whatever
 * strict semver rejects rather than throwing on it. `loose` is load-bearing:
 * the backend accepts leading zeros, so `01.2.3` is publishable and its major
 * is 1 there, while strict semver rejects it outright. Anything with no
 * version in it at all sorts as `0.0.0`.
 *
 * Do not call this on a raw git ref. Coercion picks up the first number-like
 * run anywhere in the string, so a branch named `release-2024` would become
 * `2024.0.0` and outrank every real version. Pull the version out of the ref
 * first — see `gitRefVersion` in `resolve-packages.ts`.
