Preserve Claude model and thinking preferences (#2912)

* fix(agents): preserve Claude thinking selections

Model switches now resolve thinking against the target model's saved preference instead of resetting to the catalog default. Claude owns its configured-model defaults and legacy Fable alias handling, while persisted permission modes remain unchanged.

* chore(claude): tag Fable compatibility shim

* fix(app): resolve persisted model aliases

* fix(models): preserve aliases for older clients

* fix(models): hide compatibility aliases from listings

* fix(settings): hide compatibility model aliases

* test(claude): cover legacy catalog entry

* test(app): expect mock thinking controls in schedules

* fix(app): preserve queued thinking preferences

* fix(app): reconcile schedule provider snapshots

* fix(app): preserve schedule model selections

* fix(claude): preserve exact configured model ids

* fix(app): preserve committed thinking preferences

* fix(app): preserve aliased schedule thinking
