v1.15.2

Fixed

• Tool descriptions and the runtime low-saving nudge no longer reference tools removed in
  the 3-tool strip. MinifyFile, OutlineCSharpFile, and the nudge pointed the model at
  focus_method, and TraceDiRegistrations referenced trace_implementors — none of which
  are registered tools, so a model following that guidance reached for a tool that doesn't
  exist and fell back to reading the whole file. They now point at outline_c_sharp_file
  plus a narrow Read. OutlineCSharpFile and MinifyFile also lead with an imperative
  trigger ("call this first before reading a C#/VB file over ~50 lines") so the host model
  reaches for them earlier. Descriptions only — no behaviour change (#103).
