v0.1.0-alpha.48

\n- Isolate the fff-backed local grep provider into the CLI-owned lash-search-tools crate, removing fff-search and fff-zlob feature propagation from the standard plugin stack, workbench, docs snippets, and perf harnesses.\n- Keep CLI grep behavior intact while CI and perf guard now enable zlob only through the lash-cli feature path.\n- Fix the agent-service Restate E2E mock so it skips board moves when it is not the agent turn.
