/**
 * Shared exit-status parse contract: the inverse of the `[exit code: N]` /
 * `[killed by signal: X]` markers `dsh-tool-bash` and `dsh-tool-pwsh` append.
 * Both tools' presenter suites round-trip their own renderers through this
 * parse; this spec pins the parse's own edges (marker-like output, body
 * slicing) once, at the seam that owns it.
