fix: settle the Count and Sheet Set merge

- Both PRs registered "Requires an integer between {min} and {max}." under
  their own key; keep the sheet set one, which every locale translates.
- Pin the MCP tool schema digest with the sheet set actions added.
- searchable_layer_coexists_with_outlines read glyph outlines from the
  shared atlas while other tests could re-bake it, and failed now and
  then; lay out and export under one atlas generation.
