/**
 * SessionHydrator — read persisted per-session config and push it into the
 * in-memory runtime (AgentManager + ModelManager).
 *
 * These three operations were three sibling private methods on `AgentService`
 * with subtly different signatures. They are the mirror image of
 * {@link SessionConfigService} — the latter writes user choices into the
 * config store, this hydrator reads them back out before a turn runs.
 *
 *   - `workspace()`  — apply persisted `workingDirectoryOverride` to AgentManager
 *                       and ensure the directory exists on disk
 *   - `model()`      — apply persisted `modelOverride` via ModelManager
 *   - `thinking()`   — resolve effective thinking level (request override >
 *                       per-session override > agent default) and apply
