fix(issue-30-33): review 5ec8ef33 - a multi-line codex draft is not an empty box, blocked notices reach the loop while the job runs, and both clocks are labelled on every close path

- R1 (P1): without rules the input region runs from the last prompt line to
  the end of the pane; only a last line matching the adapter's footer pattern
  (codex: `  <model> · ~/<cwd> · …`) is dropped, so a draft on a second line
  keeps the nudge withheld.
- R2: while the synchronous submit runs, a relay thread finds the job it
  registers (same session, created since the submit) and prints its
  stalled:/stall_watch: notices; before, they appeared only after the job.
- R3: the broker-unavailable disk wait that runs into the deadline is the wall
  clock: wall_clock_timeout (caller rc stays 3).
- R4: a state_change_seq change seen right before the judgement restarts the
  idle window (decision 9: S seconds of continuous idle).

Regression tests are the reviewer's reproductions, each with its passing
twin; the wrapper-level #30 tests now use this environment's broker instead
of the #18 harness's public default.
