docs: purge chain-of-thought leakage from prose

Delete design-session citations (decision/audit/plan ordinals, stack
positions), change narration, review choreography, and reviewer-addressed
justification from comments, JSDoc, docs, READMEs, Agent Notes, tests, and
generator templates; restate every affected fact as current-state contract
prose. Fix generated docs at their sources and regenerate the catalogs and
cordis-surface regions; re-paste type-equiv blocks; update every bilingual
counterpart and re-record the pairs. Record the citation rule in the
committed-artifact-citations Agent Note.

 `id` gives the entry a stable identity so the loader can tell an edit to an existing entry apart from a removal plus an addition. `disabled: true` unmounts a plugin without deleting its entry — flip it back and the plugin (and everything PENDING on its services) loads again.
 
-Groups nest a sub-list of entries that load and unload as one unit, and `isolate` gives a group its own instance of a service name — two groups can each see a differently-configured `bash` without affecting each other. Those are worth knowing about before you need them; the [Cordis primer](../cordis-primer.md) and the [service isolation example](../user/develop/framework/service.md#service-isolation) cover the details.
