feat: persist full review output to disk and render in expandable view

Review text was truncated to 500 chars in the chat message body with no
way to access the full content — once a review exceeded that limit it was
lost from the UI. Now the full review body is rendered in the expanded
(Ctrl+O) view like the implementation tool-call tree, and can optionally
be persisted to disk per-loop.

Changes:
- Add saveReviews config flag + reviewsDir path option
- Add loop-start prompt to opt into saving reviews to disk when
  auto-review is enabled (skipped when explicitly set in YAML)
- Pass full reviewText via message details instead of inlining a slice
- Extend ralpi-progress renderer to show full review body when expanded,
  dim hint to expand when collapsed
- Add saveReviewToFile() writing to .ralpi/reviews/<prdKey>/<taskId>.md,
  mirroring the per-loop reflections layout so many loops don't collide
