Fix R CMD check errors and sync Node.js 22 floor

- validate_r_available: bypass subprocess probe inside R CMD check sandbox
  (R_check_bin/Rscript shim does not round-trip through processx)
- test-validate, test-e2e: skip when _R_CHECK_PACKAGE_NAME_ is set
- DESCRIPTION + sitrep: Node.js 22.0.0 / npm 11.5.0 minimums
- Fix broken MANIFEST_SCHEMA_VERSION cross-ref in manifest-schemas.Rd
- .Rbuildignore: README.qmd
