feat(500): who decides what - the agent settles what only it can see, the operator decides direction (#5494)

The operator's line (2026-10-09), reconciling their 2026-09-21 ruling
(#4218, "you are the judge") with "not that Claude should make all
decisions": judging covers the work and its records - facts, findings,
measurements, whether work is done - and direction stays theirs:
priorities, what the thing should be, trade-offs only they can price,
anything they live with, and every act hard to undo or facing outward.

- reply_shapes: a one-line form in the core (every turn), the full text
  in the asks slice (where a question gets handed back). Slice budget
  1400 -> 1600 for it.
- reporting-back "You are the judge": "the operator reads the decision -
  they do not make it" replaced; the line is drawn by who can see the
  evidence, not by how hard the call is.
- plugin version minted.
