feat(model-overlays): add fable-5, opus-4-8, and sonnet-5 overlays + resolver mappings

model-overlays/ had no entry for the current Claude generation, so every session on a Claude 5 family or Opus 4.8 model fell through to the generic claude.md nudges. Adds the three overlays with resolver mappings and per-overlay tests; generated output for the default host is unchanged (overlays activate by detected model). Closes #2509. Contributed by @chrisquorum (PRs #2246, #2243, #2247). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

+ * results, assessment-vs-action boundaries, and delegate independent work.
