sx-tree MCP file ops broken this session (Yojson Type_error "Expected
string, got null" on every file-based call — sx_read_subtree,
sx_find_all, sx_replace_by_pattern, sx_summarise, sx_pretty_print, even
sx_load_check on existing files works but summarise fails). Can't edit
integration.sx to add before:init/after:init dispatch. Additionally 4
of the 6 tests fundamentally require stricter parser error-rejection
(add - to currently parses to (set! nil ...); on click blargh end
accepts blargh as symbol expression) — out of single-cluster budget.
