Add kw_only to large frozen report/response dataclasses

[adamtheturtle]

Summary

DatabaseSummaryReport, TargetSummaryReport, TargetRecord, and Response now use kw_only=True with frozen=True. Constructors in this repo already use keyword arguments.

Smaller frozen types in reports.py (TargetData, QueryResult, TargetStatusAndRecord) are unchanged.

Testing

Full suite was not run here due to local torch/httpx environment issues on this machine; constructors were verified to use keywords via code search.

Note

Medium Risk
This changes the public constructor signature of several exported dataclasses (kw_only=True), which is backward-incompatible for any external callers using positional args. Internal call sites appear to already use keyword arguments, so impact should be limited if consumers follow the same pattern.

Overview
Makes DatabaseSummaryReport, TargetSummaryReport, TargetRecord, and Response keyword-only dataclasses by adding kw_only=True while keeping them frozen=True.

This prevents positional construction of these types (a small API tightening), while leaving smaller frozen report types unchanged.
