`fabro-hooks` ran the legacy executor's hooks; Petri's Attractor steps
run Fabro's hooks now, so nothing in the workspace uses the crate. The
engine freeze (the CI workflow, the two scripts, and the AGENTS.md and
fabro-petri README sections) guarded the engine half of `fabro-workflow`,
which the previous commit deleted.

fabro-model's ids and billing rollup now live in fabro-types, and its
pricing, catalog, provider TOMLs, and legacy index are replaced by the
lithos built-in catalog plus the Fabro policy layer.
Regenerate the configuration reference for the `[llm]` overlay and
`metadata.fabro`, and rewrite the SDK, models, and integration docs for
the lithos provider and model shapes.
