review(tool-goal,llm-replay): address ds-review-bot round one

- fromRequest placeholder: the last two braces of a consecutive } run now
  terminate the placeholder, so patterns may end with a brace quantifier
  (bot warning; the truncated pattern could even silently mis-match since
  an unclosed { is literal in JS regexes)
- document that derived JSONL entries pass through the same resolution
- widen ToolRunContext/deferContext seam docs beyond composite-only usage
  (source JSDoc, README pair, core-data-structures type-equiv blocks)
- pin direct-human blocked as uninstructed, completing the
  goal-round/direct-human x complete/blocked test quadrant
