test running / reporting improvements (#797)

**CI/CD improvements (validate.yml):**
- Add test reporter (`ue-foundation/test-reporter@v2`) for all three platforms, rendering JUnit test results directly in PR check runs
- Add "Trust workspace" step on Windows to fix git safe.directory ownership issue with self-hosted runners
- Clean stale report files before each test run to prevent false failures from leftover XML
- Broaden `paths-ignore` to skip builds for non-code changes (`*.md`, `LICENSE`, `.gitignore`, `docs/**`)

**Test improvements:**
- Convert `CHECK` to `REQUIRE` in several test suites (projectstore, integration, http) for fail-fast behavior
- Mark some tests with `doctest::skip()` for selective execution
- Skip httpclient transport tests pending investigation
- Add `--noskip` option to `xmake test` task
- Add `--repeat=<N>` option to `xmake test` task, to run tests repeatedly N times or until there is a failure

**xmake test output improvements:**
- Add totals row to test summary table
- Right-justify numeric columns in summary table
