copilot-swe-agent[bot] 387b02acf5 Fix all tests with unintentional error changes
Added explicit types arrays to tests that had NEW errors after the default change:
- tsc/incremental: react-jsx tests now have types: ["react"]
- tsbuild/moduleResolution: type-reference-resolution test now has types: ["sometype"]
- tscWatch/resolutionCache: tests now have types: ["node"]
- tsserver tests: added types for node, lib1, lib2, typings
- compiler tests: jsDeclarationsTypeReferences and typeReferenceDirectives tests now have explicit @types directives

All tests now pass with only expected errors (no unintentional changes).
