tests: the full suite's seven failures on lang/foundations - one compiler fault and six stale expectations

- the test runner re-makes every state between tests again: since 12fdc07 a state is made by its getter on
  first use, so re-running L_init_globals left the last test's state in place (state/tested failed its
  second test); @L_reset_states forgets every lazy state, and the runner calls it before each test
- diag_json_case counts errors, and an absent @Ref / @Tint / @OneOf target is a warning since d82dc31:
  ref_unknown is 1 error and node_bad 8
- schema_hash.ludic prints 1: a bool is 1 or 0 as text (random_plain's 1 1 1)
- permap_check_case looks for the unit warning without the quotes the JSON escapes
- baked_test's inputs-hash test makes its directory: each test has a temp directory of its own
- ludic deps prints phase 25's five counters too
