docs(hindsight): correct recall_types scope — tool path is also narrowed

The original change's description and README claimed the per-call
hindsight_recall tool was unaffected by the new observation-only default.
That is inaccurate: hindsight_recall reads the same self._recall_types
instance attribute as the auto-recall prefetch path, and RECALL_SCHEMA
exposes no per-call types argument, so the model cannot override it.
Narrowing the default narrows BOTH paths.

Corrects the README behavior-change note, the config-table row, and the
get_config_schema description to reflect that recall_types applies to
both auto-recall and the hindsight_recall tool.
