matched_tools claimed every surface tool matched even when entries were
registry stubs with no live MCP metadata, and unmatched_tools was
hardcoded to 0. Coverage now excludes stubs from matched_tools, reports
them as unmatched, and a registry JSON parse failure warns instead of
silently producing a stub-only snapshot. The schema catalog policy
invariant is relaxed to match the honest accounting.
