Adds tests/GameCult.Caching.Tests/stryker-config.json and the scope section of docs/mutation-testing.md (why Caching before Networking, measured cost: 243 mutants narrow, 84.91%, ~1.6 s/mutant, ~1 h full), and six tests in ElementIdWalkTests.cs that kill the real CultElementIds.cs survivors (narrow rerun 94.74%). The remaining 12 survivors are hand-checked equivalents, recorded in the doc. Test-only, no production change.

Follow-up: cultlib-gaps:follow_up:mutation-testing-scope. Report: variants:cut_report:cut-cut-caching-mutation-scope.h1.
